Maybe it needs fixes elsewhere as well, but it's via package.el that the
problem is usually exposed.

Depends how you do it.

package.el does try to do that nowadays (in
`package--load-files-for-activation`).

It doesn't/can't handle all situations, but it should solve most of the
common issues.  Since it's virtually impossible to fix it 100%, we
depend on reports of actual problems in order to know what still needs
to be fixed (they need to be reproducible so we can figure out exactly
what happened, since it's not always obvious how best to avoid the
problem).
