When presented with an either-or decision like "Doing <X> will make $M but
doing <NOT-X> will save $S" then in most public companies $S would have to be
more than $M x 2 before <X> will stop happening.  In this case $S is not even
a notable fraction of $M so it's not even worth discussing.

Somebody here said router design was a political process.  I disagree.  But
networks are complex systems owing their existence (and their nature) to an
ever shifting matrix of politics, economics, and physics.  And, Heraclitus'
maxim is very much appropos here.  The target for a router designer is moving.
