I don't think so. You already need the / filesystem, and with today storage
sizes, if you can hold that, you can hold the whole system, period. Even on
any embedded that can run Debian.
The last time I've seen a split done due to small / was Maemo ten years ago.
And guess what? They didn't use / vs /usr but hacked something where both /
and /usr were on the small mmc while big /opt hold most of the files, with
symlinks from /usr. That's because their needs were different from those of
Ken Thompson in 1971.
A reasonable and often important split is keeping /+/usr apart from a box's
main purpose, be it /home, /srv or /var/lib/postgresql -- but in any case
both / and /usr will be on the same filesystem.
Thus, I'd say /usr is pointless on any machine we can reasonably support.
