Why not just map block list to one, defined privacy list?  It's name
would be well-known, it contents would be expected (only
type='jid'/action='deny' entries) and clients choosing full privacy-list
interface would just select and modify some other lists. Adding
non-blocklist-compatible  entries to the blocklist privacy-list would
cause undefined behaviour, but this would be a single case for which
there could be exception added even in clients not implementing block
lists.
