I can see both sides of this argument. But I think Daniel is right in many ways --- ASDF is way down at the bottom of the dependency stack for the common lisp community and so the expectation of it remaining stable is pretty important.
Probably, though, to avoid stagnation, we need to soon begin a branch that will lead us to ASDF 3.
We need to find someone who wishes to lead us on that journey, though, since Faré has announced his desire to move on to something different.
