Regressions of such magnitude can veto such changes, especially when
they hit everyone, not just those who are highly dependent on the
profiling tools the proposal is concerned about.
I can only concur. Say what you want about Phoronix benchmark, but
they consistently benchmark different distributions And Fedora
consistently is lagging behind. Latest article is at

Slowing Fedora even further is really undesirable.
