So, how much work is it to reinstall axiom or friCAS, or open-axiom?  1 minute?
2 minutes?

I believe, the question is rather: do we want to drift apart at the user level?
I don't.  If the algebra starts to diverge, do you think the number of
contributers will triple?  As far as I can see, (i.e., among the mathematicians
I know of) the number of axiom users has rather decreased since the forks,
although it was increasing before.

I believe that forking the fundamental workings of axiom (i.e., the algebra,
the compiler) in an essentially incompatible way would be a disaster for axiom.
In this case, axiom would be lucky if only one fork would survive.  Otherwise,
we will have three nearly dead CAS.

At least, it doesn't seem that the "key players" read all the lists.  Otherwise
Tim would have known that SAGE runs Waldek's branch, there was a lengthy
discussion of the reasons for that.
