I assume I'm missing some context here, but why does this need to be

works?

Honestly, the less we have to mess with user-mode tooling, the better.

We've been *so* much better off moving most of the module loading
logic to the kernel, we should not go back in the old broken
direction.

I do *not* want the kmod project that is then taken over by systemd,
and breaks it the same way they broke firmware loading.

Keep modprobe doing one thing, and one thing only: track dependencies
and mindlessly just load the modules. Do *not* ask for it to do
anything else.

Right now kmod is a nice simple project. Lots of testsuite stuff, and
a very clear goal. Let's keep kmod doing one thing, and not even have
to care about internal kernel decisions like "oh, this module might
not be a module, but an executable".

If anything, I think we want to keep our options open, in the case we
need or want to ever consider short-circuiting things and allowing
direct loading of the simple cases and bypassing modprobe entirely.
