The hba syntax changes between 8.3 and 8.4 continue to annoy me to this
day, so I'd like to avoid these in the future, especially if they are
for mostly cosmetic reasons. I think any change should be backward
compatible to all supported versions, or alternatively to 8.4, since
that's incompatible with 8.3 anyway. (Those two will be the same before
9.3 goes out.)

So, in my opinion, krb5 could be removed, assuming that gssapi is a full
substitute. But ident-over-unix-sockets should stay, at least until 9.0
is EOL.
