I think sharemgr was created to speed up the case of sharing out very high numbers of filesystems on NFS servers, which otherwise took quite a long time. That's not to say that there might not be other problems with scaling to thousands of filesystems. But you're certainly not the first one to test it. For cases where a single filesystem must contain files owned by multiple users (/var/mail being one example), old fashioned UFS quotas still solve the problem where the alternative approach with ZFS doesn't.
