Right, I wasn't talking about how many steps/messages the negotiation takes=
. I just meant that if all negotiation of the mapping table happens just on=
ce (before VERACK) and that negotiation itself happens without use of short=
commands, then there is no need for re-negotiating short commands after th=
ey are already in use. Nothing concrete, but I can imagine that that may si=
mplify some implementations.
