What happens if a table was serialized with one of these objects, but now you're loading it in a session in which e.g. UUIDs isn't loaded? I think this is probably breaking, unfortunately, since before you'd get back UUID types, whereas now you have to change your code to load UUIDs to get it.

That's a valid point, thanks for bringing it up. Do you think it's worth continuing with this change but bump major rather than minor? Or should we abandon this change for now?

[ericphanson]

These are pretty light packages, and are in the sysimage anyway until v1.11, so to me it doesn’t feel worth all the compat bumps it will cause. I think it’s worth waiting until there’s other reasons for a breaking change, or some big reason why having them is causing problems.

[baumgold]

Sounds good. I'll put this PR on hold for now. Thanks for the feedback.

Why not keep the existing Julia version compat and do this instead? https://pkgdocs.julialang.org/v1/creating-packages/#Transition-from-normal-dependency-to-extension
