Yes, I looked at fiveam-asdf before doing this. I think the two have
very different goals: fiveam-asdf is a comprehensive integration of
FiveAM into ASDF, while what I am proposing is a minimal signal
protocol that is easy to add to any testing library.

What is the use case for this? It would be a lot more complicated for
test libraries to implement, and I cannot think of any scenarios
where I would need that.

Yes, that is what my patch to FiveAM does:
