You'd think so.  I recently changed my T2500 to offer PEP tones last
due to problems in making V.32 connections after the T2500's firmware
was upgraded (details in comp.dcom.modems).  I sent out a message to
all of my neighbours saying "anyone have problems setting s50=255
before calling imax?"

It turns out that most neighbours were already doing this as a
matter of course for all PEP connections - it was in their standard
Dialers (or equivalent) entry.  One wasn't doing it, but didn't think
it would be a problem.

So it wasn't as bad as you might expect.  Maybe it's worth polling your
neighbours and seeing who would have problems if you offered PEP tones
last.
