> I am afraid that the specification would become needlessly complex, if we are to suggest that padding outside of QUIC packet is a possibility.

Many other implementations didn't initially work against Neqo (which pads outside) and the Wireshark QUIC dissector does not currently handle it either. If the spec doesn't say anything then future implementations are bound to incorrectly handle outside padding. People are bound to assume it is not allowed if the spec says nothing, or just not consider the possibility of it.
