It's not guaranteed no, which is why we store signed sub-messages as byte
arrays instead of typed submessages. In practice though, most
implementations do seem to serialise things the same way. I recall Python
used to be an odd one out, unsure if it still is.
OK, I guess we can boil this down more simply. BIP 70 uses protocol buffers
because I designed it and implemented the original prototype (with lots of
input from Gavin and an earlier proposal by sipa). I used protocol buffers
because, beyond all their nice properties, I used to work at Google and so
was very familiar with them.
