Yes, but /etc/rc doesn't:
# prune quickly with one rm, then use find to clean up /tmp/[lq]*
# (not needed with mfs /tmp, but doesn't hurt there...)
(cd /tmp && rm -rf [a-km-pr-zA-Z]* &&
find . ! -name . ! -name lost+found ! -name quota.user \
! -name quota.group -execdir rm -rf -- {} \; -type d -prune)
You are right that a /tmp-based vi.recover wouldn't be wiped out by
/etc/daily, which is interesting as I hadn't thought about that possible
problem yet, but a reboot will still kill your vi(1) files.

vi(1) is pretty usable. And, according to an Undeadly poll, while
vi-variants lead, Emacs is also quite popular - as well as simpler
editors (joe, nano, ...).
I use vim myself, and it doesn't use /var/tmp/vi.recover so at least
that problem won't occur if you are the only user and use vim.
