Also, right now tests are going to fail since they don't include the noop package so the global interface variable is nil, but that's irrelevant to what should be checked right now.

My main comment is don't put this new information in the context in order to get it to where it needs to go in non-mainline parse contexts. The catalog is a better target for that.

Otherwise I think this plan seems sound.

I think the hooks stuff is harmless enough to leave in with this batch of changes.

The only additional structural change you should make is to make ExtensionHook into an interface rather than separate structs with func fields.
