As we remove the concept of a global "known/supported" feature set
in LDK, we should also remove the concept of a global "required"
feature set. This does so by moving the checks for specific
required features into handlers.

Specifically, it allows the handler peer_connected method to
return an Err if the peer should be disconnected. Only one such
required feature bit is currently set - static_remote_key, which
is required in ChannelManager.

It's not obvious to me why we wouldn't also disallow peers that don't support payment_secret, since it looks like we'll fail payments that don't have one.

Payment_secret is really between us and the sender - we can have a channel with someone who doesn't speak payment_secret, and our counterparty can't pay us directly, but we can still receive funds via them.

It appears our code is already correct here, but its also nice to
add a quick safety check in `channel.rs` which ensures we will
remain idempotent.
In the next commit we'll enforce counterparty `InitFeatures`
matching our required set in `ChannelManager`, implying they must
be set for many tests where they previously did not need to be (as
they were enforced in `PeerManager`, which is not used in
functional tests).
As we remove the concept of a global "known/supported" feature set
in LDK, we should also remove the concept of a global "required"
feature set. This does so by moving the checks for specific
required features into handlers.
Specifically, it allows the handler `peer_connected` method to

In the next commit we'll enforce counterparty `InitFeatures`
matching our required set in `ChannelManager`, implying they must
be set for many tests where they previously did not need to be (as
they were enforced in `PeerManager`, which is not used in
functional tests).
As we remove the concept of a global "known/supported" feature set
in LDK, we should also remove the concept of a global "required"
feature set. This does so by moving the checks for specific
required features into handlers.
Specifically, it allows the handler `peer_connected` method to
return an `Err` if the peer should be disconnected. Only one such
required feature bit is currently set - `static_remote_key`, which
is required in `ChannelManager`.

Payment_secret is really between us and the sender - we can have a channel with someone who doesn't speak payment_secret, and our counterparty can't pay us directly, but we can still receive funds via them.

As we remove the concept of a global "known/supported" feature set
in LDK, we should also remove the concept of a global "required"
feature set. This does so by moving the checks for specific
required features into handlers.

Specifically, it allows the handler peer_connected method to
return an Err if the peer should be disconnected. Only one such
required feature bit is currently set - static_remote_key, which
is required in ChannelManager.

It's not obvious to me why we wouldn't also disallow peers that don't support payment_secret, since it looks like we'll fail payments that don't have one.

Payment_secret is really between us and the sender - we can have a channel with someone who doesn't speak payment_secret, and our counterparty can't pay us directly, but we can still receive funds via them.

LGTM after squash.

It appears our code is already correct here, but its also nice to
add a quick safety check in `channel.rs` which ensures we will
remain idempotent.
In the next commit we'll enforce counterparty `InitFeatures`
matching our required set in `ChannelManager`, implying they must
be set for many tests where they previously did not need to be (as
they were enforced in `PeerManager`, which is not used in
functional tests).
As we remove the concept of a global "known/supported" feature set
in LDK, we should also remove the concept of a global "required"
feature set. This does so by moving the checks for specific
required features into handlers.
Specifically, it allows the handler `peer_connected` method to
return an `Err` if the peer should be disconnected. Only one such
required feature bit is currently set - `static_remote_key`, which
is required in `ChannelManager`.
