It's confusing to say the least. When one has to patch a bundle, they
won't know which one to patch.

No, I am not saying that IPS is the only way. I am saying that when IPS
is used, how does rm/cp way of installing things work?

There is no such assumption in code, you know that very very well. I am
only worried about having a directory which has partial list of modules.
I am sure there are better ways to remove all bundles for a feature that
just removing a directory.
