Actually, I had already asked. This is case gnu.org #690921.

Now, whether impolite or dishonest is not for me to judge. I am just
following the FSF's request. And FYI, all of this has been taking
hours of my time, soon to add up to days. I don't think I should
be asked to make a list of all involved parties, track them down,
and ask them whether they agree to the change or not. Especially
since the license they chose to use explicitly included permission
for us to do so.

That being said, if someone would like to step up for the group,
and volunteer to inform the various parties involved, I would
entertain the idea of backing the change out - provided that
the FSF is OK with that. And if we could also get them to assign
their past changes to the FSF, that would be awesome.
