Does anyone do this kind of analysis but across well used libraries for a language?

Similar to how in this article they compiled a whole bunch of rust projects and flagged up the areas that were slow to compile for specific crates, does anyone do analysis that says this dependency shows up in a lot of hot paths when running benchmarks or test code and then get someone to apply this kind of systems level thinking to it?

It seems at least one fix was for a hashing library dependency and may have wider benefits, but surely that applies to more things too?
