IMO no organization has "deep legal knowledge" of these issues,
because as far as I'm aware something like this has never been done
and tested in court.  Really there are only a handful of legal cases
at all that deal with copyleft and FOSS relicensing.

There is no end of lawyers who will hand-wave on the issue.  I think
the bottom line is that doing something like this is legally risky,
because until something like this has been done successfully many
times it is novel.  You're never going to find a lawyer who will sign
off saying "this is safe and definitely legal."  The only way you
could make something like this risk-free would be to get governments
around the world to pass laws setting up requirements for
FOSS-relicensing without the consent of all contributors.

The best we can do is mitigate risks, if we elect to do something like
this.  That can include being transparent, giving notice, having a way
to opt out, and so on.  Then when somebody sends us a cease and desist
notice we just tell them no problem, their contributions will be
treated as v2-only.  That doesn't completely prevent them from suing
us, but it would mitigate the impact, and probably make it unlikely
that most would sue in the first place.  Really, with something like
this that is the best you're ever going to be able to hope for.

If you don't want to do something unless a lawyer can guarantee that
it can't be found to be a tort by a court, then you definitely don't
want to pursue this change, unless we only make it forward-going for
new contributions and carefully track existing code, and I doubt that
will ever be very practical, so you might as well just give up and say
we'll be v2 forever because that's how things were set up 20 years
