I don't know the devs' familiarity or positions on it (or the history
of it here), but it's potentially relevant if you're looking at udev
and the /{bin,sbin,lib} vs /usr/{bin,sbin,lib} split.

Walter Dnes (very active over in gentoo-user) has put a lot of work
into testing and documenting mdev as an alternative for udev. There's
been a good deal of success there, up to and including it working with
GNOME 2. The work's been documented on the wiki:
