This has been discussed in the past. One problem is that there is no
cross-platform standardization of what the name following % can be.
So we couldn't do much better than accepting it on faith and storing
it as a string, which is not very nice. It's also very unclear how
such a marker should affect the semantics of inet operators and
functions.
Maybe someday somebody will get motivated to try to surmount those
problems, but don't hold your breath.
