I think I would really only be interested if it was a generic
feature that worked for all target-* CPU frontends (and which
wasn't too intrusive, and was enablable at runtime, not compile
time).
Wanting to do this sort of tracing is quite a common thing I think;
the difficulty is doing it as a long-term maintainable generic
feature.
