Agreed, this is a bug, however there is a trivial fix. Note that this isn't
architectural, it's simply a mechanism change.
Note that Ran still needs to confirm this bug.
What's needed is a mapping from FQDN -> (I, {L}) and FQDN -> (I, {LP}).
These are actually combined, but writing FQDN -> { (I, {L | LP } ) } seems
like a bit much to parse. ;-)
Implementing this is not hard. Let me propose a fix:
An IL record that provides a FQDN -> (I, L) mapping and an ILP record that
provides a FQDN -> (I, LP) mapping. Thus, the records would look something
like:
Www.google.com IL iiiiiiii iiiiiiii llllllll llllllll
Or
Www.google.com ILP iiiiiiii iiiiiiii myfavorite.subnet.com
Note that in the latter case, L records as proposed are still useful.
Ran is welcome to adopt this fix (or not ;-).

Except that identifiers aren't globally unique, so that doesn't work.
