Depending on the host lisp you are using, couldn't you wrap the calls

I could, but since I want per-library numbers, I would need to
reconstruct that information afterwards...

Yes, I am afraid that is correct.

This is yet another problem that comes from the fact that the build plans are linear, instead of hierarchical -- for example there's no subsequence that is identifiable as being the set of operations for a particular module.

Logically speaking, there's a tree structure in the build process that is what you need, but I don't believe that there are any facilities in ASDF to recover that tree structure.

This may be the best you can do.
