In contrast to any 'something<' mapping, a '<' mapping cannot be unique
Thus, '<' mappings are thus just an append to target, which is exactly
what we get when trimming empty prefix ''.
Otherwise, given mapping
{ "<": "storage/backups/app-srv" }
Before (clearly a conflict)
zroot => storage/backups/app-srv
storage => storage/backups/app-srv
After:
zroot => storage/backups/app-srv/zroot
storage => storage/backups/app-srv/storage
However, mapping directly with subtree wildcard is still possible, just
not with the root wildcard
{
"<" "storage/backups/app-srv"
"zroot/var/db<": "storage/db_replication/app-srv"
}

While filesystems is also not the right term (since it excludes ZVOLs),
we want to stay consistent with comments & terminology used in docs.
