Well, if you're willing to depend on that, then there's no need for the
WITH ENCRYPTED PASSWORD variant syntax: the existing syntax WITH
PASSWORD could do it all, just by checking to see if the supplied
password string looks like it's already been md5-ified.

The real trick would be to get this to happen during a COPY into
pg_shadow --- if we did that, then dumps generated by 7.0 pg_dumpall
would still work. Perhaps a trigger on pg_shadow insert/update is
the right place to check and md5-ify the password? (If that's in place
then neither CREATE nor ALTER USER would need to do anything special!)
