That I agree with - making a v6 that sends a minimum-sized packets,
and where the readers just always try to read the maximum size.

That said, this is not exactly something high-performance, and copying
the pointless padding to make a fixed-size packet isn't a big deal.
We're talking just 240 extra bytes or so (NAME_MAX is 255, and most
names are obviously much shorter), so I do believe that we might as
well wait unless there are other good cleanups too.
