I think the main license we lose by stating that it
has to be accepted by both groups is the Apple Public Source license.
Personally that doesn't bother me and since nothing in PEAR that I can
find is under this Apple license, this seems like an acceptable compromise
to get RMS and the FSF to say good things about PEAR.
I don't think that this will be a problem. Various people are working on
Apple-specific PECL extensions, but they will only be linking against
Apple code, not distributing it. So, basically, the only thing we'd be
locking out is contributions from Apple itself -- none of which seem to
be on the horizon.
