I think this is a bad idea. PL/Java will use either shared memory or a socket to attach and 
as you already mentioned, when using C, a gdb will attach directly using the pid. I wouldn't 
be too surprised if Perl, Python, and PHP all have a similar solution and thus have no 
benefit from additions to the FE/BE protocol. IMO, debugging should be language specific and 
take place in a separate channel. There's no gain whatsoever mixing it with the FE/BE protocol.
