Two comments:
1) Although yahoo groups has a lot of mailing lists, it is still one
set of server software to fix.
2) If anyone knows the gmane folks they could probably run a perl
script that would answer the sets sender question over the
largest data set we are likely to get.

I doubt we really need to survey list operators. Instead,
survey the
software used.
This would include: Sets Sender? Sets MAIL FROM?
YahooGroups n y
Mailman y y
ezmlm n y
Majordomo 1.x y y
Majordomo 2.x y y
Interesting data, thanks. I still think it's relevent to
ask how many
lists out there are operated by each class of server, in
other words,
how many actually have to change. I would guess that Majordomo
accounts for a huge chunk for example.
Hard to know, with so many mailing lists being private.
Googling for the
constant strings used by majordomo and mailman web frontends returns
130 or so results for majordomo and 130,000 for mailman. Let me step
out on the limb and claim that mailman is NOT a thousand times more
popular than majordomo.
