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.
