Of course I realized this issue pretty much from the beginning when we
added support for it to the tree.

The problem with forcing ALL and ALL_KMODS to select packages is that it
makes it difficult to deselect a package afterwards.
Also unlike the profile case, those options are typically selected when
you start building a configuration for a device, not so much after
you've already configured everything.

So while there are superficial similarities with the profile issue,
there are enough differences in how it gets used by users that we should
treat it differently.
