Well of course software has to change to implement new RR types, because 
old software wasn't going to query for those RRs and if it got those RRs 
back in a response it would have to ignore them.

But DNS itself shouldn't have to change to implement new RR types, more 
than (perhaps) adding a line to a table that says RR type NN has ASCII 
name XX and the following types of parameters. And that table should be 
globally and securely accessible. Encode the table in DNS somehow, put 
it in the root zone or other zone managed by the root, give it a very 
long TTL, and sign it with DNSSEC.
