I'd be inclined to just let quotas take care of it, because a snapshot is really just another way of using space. As a general principle I think an operating system should restrict physical resources (disk space, physical memory, CPU time) as necessary, but not put any limits on logical resources (e.g. files per directory, mappings per address space, or integer multiplies per function call). Limits on logical resources tend to be very annoying to deal with.
