It's the same on Debian and its derivatives, FWIW.

Out-of-tree, backported or otherwise weird modules go in a different
subdirectory of /lib/modules/<kernel-version>/. In particular, I think
I've seen /lib/modules/<kernel-version>/updates/ used for backported
versions of newer graphics drivers which should take precedence over the
in-tree version.

This seems like moving things around for the sake of moving things
around. If Fedora, Debian and Mageia all use
/lib/modules/<kvers>/kernel/ then it seems reasonably likely that
everyone else does too.

Also, the kernel/ subdirectory does exist for a reason: it's where
in-tree modules from that kernel go (as opposed to backports of newer
drivers, or out-of-tree modules like kdbus).
