While this reverts regressions, this has to cause "new" regressions. The problem here is that the previous regressions are relatively recent, still, and the previous regressions are ***much worse*** than the slight newer regressions that fixes the older regressions. Note that this is not regressing the packages that are "newly" regressing prior to the versions they were beforehand. They are now currently pinned in a pessimistic manner, to correctly fix the problems in the way that was initially intended.
