Commpare should be Compare. Sure, there's backwards compatibility to consider. Even if it is decided to not fix this, at least there will be a rejected issue for this that others can find in the future.
I noticed this in PyQt5 5.15.3 (uses Qt 5.15.2) in Qt3DRender.QAbstractTexture.ComparisonFunction.CommpareNotEqual. Also found a reference at the link below.
Anyways, maybe just checkout the full tree for a few different places where development will continue and grep -i commpare to try to catch them all.
