[Pgi-wg] Profiling vs new specs

Here, "extra information can be agreed upon" is right - but when I
understand it right it is exactly that we here don't like to support the
"old relics / old way of doing it still" or carry it around although it's
deprecated,  and not provides backwards compatibility anyway, and is not
intended to use by production middleware....

...however in this sense, we may can profile "the old relics" out which
point again to the question of how much we actually have to profile out  /
develop new.

Take care,
Morris
