I think that this should wait until Pablo verifies that it is indeed the implementation that should be changed.

@art049 did you verify that the new output after this PR works the same with perf?

@terryjreedy since the relevant docs here are the external perf map specification, not the CPython docs, it seems clear that the implementation in CPython should match the specification. There is no option to change the specification, we don't own it.
