CheckUnionTypes is not true on bleedingEdge, so checkBenevolentUnionTypes which is stricter shouldn't be true too.

checkBenevolentUnionTypes will never be true by default, that's why it's "benevolent".

But I'm kinda worried about someone using the config
checkUnionTypes: false
checkBenevolentUnionTypes: true
what should be the behavior ?
- checking both ?
- checking none ?
- only checking the benevolent ?
- throwing an error ?
