Yes, that is the situation, but it the asksign is highly annoying
since it is triggered in many unneeded cases, Maxima 5.17.1 introduced
them in some new cases, like now
limit(a*x,x,0);
for example will ask for the sign of a while 5.16.3 did not. That
coupled with some other regressions that were not fixed in 5.17.x at
least convinced me to sit out this Maxima upgrade and see how 5.18.x
(or whatever comes next) fares.
Given a choice between Pan-Axiom, Maxima and Reduce for the role of
symbolic calculus in Sage these days I personally would pick FriCAS
over the other choices. But since all of the above do not solve the
fundamental problem of using pexpect I think that in the long term we
will come up with something on our own, i.e. partially sympy and
partially our own code. That doesn't mean the interface to any
existing system will be removed, just that Maxima would potentially at
some point be made optional - should it ever come to the point where
we have something better.
