It feels weird to have this as a general option in config.php.

It should be an option for each storage defined in files_external, no? You may want to enable it for an SMB one on local network and disable it for another s3 storage? Or is that too niche?

I agree that having this per storage would be better.

Additionally, allowing the admin to set a different cutoff size instead of just disabling the cutoff altogether would be nice.

Note that there is a "mount options" system that would probably make sense to use to configure this.

They can be set with occ files_external:option <mount id> <key> <value> and then checked with $file->getMountPoint()->getOption($key, $default)

Got it. 👍
In that case, i'm closing here in favour of a "per storage" option.
