It's designed that way intentionally to aid in error detection. Parsing
the packet following its internal structure should end up exactly at the
end of the packet according to the length word. Otherwise something's
corrupted.
There are some backwards-compatibility considerations here too (the
internal structure matches pre-V3 protocol which had no length word).
But it's a perfectly fine definition and we have absolutely no intention
of "fixing" it.
