So it seems like the bar should be pretty low for this one (assuming we get the performance penalty low enough). If it were some massive or broadly impactful (or even clearly public) change then I suppose you could call the motivation weak. However, this isn't that sort of PEP.
Yes, but PEPs are not just about complexity, but also impact on users. And "impact" covers backwards-compatibility which includes performance regressions (i.e. making Python slower means it may no longer be a viable for someone with specific performance requirements). So with the initial 4% performance regression it made sense to write a PEP.
