What does "strict improvement" even mean? Many changes are not strict 
improvements, but still useful to have.

Inada pointed me to YAGNI 
(https://en.wikipedia.org/wiki/You_aren%27t_gonna_need_it) but I 
disagree with that premise: there is a large gray zone between 
"completely useless" and "really needed". My PR falls in that gap of 
"nice to have but we can do without it".

If those refactorings are rejected now, won't they be rejected as part 
of PEP 580 also?
