Shims no longer bundled after migration to v3

Hi, I am creating this issue because the 'get a slack invite' website seems to crash on email submission..
So - I've followed the migration guide and attempted to build an app with a dedicated library using the -a flag. Earlier this used to mount all shims under the /resources dist directory, but now only some? shims are mounted. I cannot seem to find any info regarding shims & this behavior in the new tooling version. What am I missing?

Expected Behavior

Shims in libraries should be in the dist of the consuming app

Current Behavior

None or only some shims are bundled in the dist

Steps to Reproduce the Issue
