Really? That wasn't the impression I got. My understanding is that if
PTC isn't a requirement, it should not exist. As a programmer, I don't
want to need to keep track of whether which implementations support my
programming style. Do we really want "ES4" and "Stackless ES4" (for
example)?

Peter Michaux put it nicely when he said:

Portability is a huge requirement for me, and if there's a valid reason
for leaving PTC out of an implementation history shows that someone
will.
