It is pedantic because an IPSP does not need an ASP Traffic Mode to be
redundant.  When acting like an SGP, the peer IPSP can distribute
traffic in accordance with the way that an ASP distributes messages to
the SGP that make up an SG.  The SE-IPSP acting in SGP mode does not
require an "ASP Traffic Mode".

Traffic Mode (the parameter) is an ASP concept.  Is is only useful to an
SE-IPSP in so much as the SE-IPSP is behaving like an ASP.  In SE mode,
it was never intended that both sides behave like an ASP at the same
time.  That is DE mode.
