#52841 was intended to make the loading of extensions be less coupled to what packages are in the sysimage but it didn't get all the way there since the
require
calls are not "recorded" for packages in the sysimage.In the following situation:
will load the ACExt in the normal case, but will not load it if B (and thus C) is in the sysimage.
This PR starts fixing that but it will still fail if the package in the sysimage ends up getting loaded from another precompiled package.
