I agree with you, I really don't like making the module loader more
complex (which is why I didn't opt to create separate sections in the
first place), and in the end this change will in some ways benefit
out-of-tree drivers too, even though it will be a bit painful now.

That aligns with how I think about this; if we want this to be a
standard thing in the kernel, we should at some point enforce it,
because it's pretty easy to ignore the warning. The good thing is that
it's not a big on/off switch, but subsystem maintainers can just
introduce namespaces when it makes sense.
