Why not Skia pathops?

[simoncozens]

Conventional wisdom is "Skia pathops is OK but has some edge cases and you should use booleanOperations because it's 'better'." But I can't find anything to back this up. Can we use this issue to collect and identify the differences?

I think anything known is probably reported here https://github.com/fonttools/skia-pathops/issues. My perception is the other way around, skia pathops are overall better, but booleanOperations is kept as the default for backward compatibility.

I think the same applies to compreffor vs cffsubr. I think we should do a major release and change all these defaults.
