It's shown to clients that ask for NAMESPACE, so there is some
difference. Dovecot probably will never internally care what about their
difference.

Well.. Since those are rarely accessed anyway, I don't think it matters
where they're located or if they're deleted/lost once in a while.

Normally the control files shouldn't be lost, dovecot-uidlist
especially.

Dovecot doesn't care if you use mixed NFS/local filesystems.
