Correct. Union types I've always seen presented as offering both union and intersection. There are cases where union is great, and where it's kinda silly. There are cases where intersect is great, and where it's kinda silly. Most of the anti- arguments I've seen for "union types" have fixated on "int && string is meaningless, and Foo || Bar is bad design, so union types are bad!" Entirely ignoring the flip side, which is int || string (valid use cases) and Foo && Bar (many many valid use cases)
well, that explains why the same person which hase a usecase for a "scalar" pseudo-type donw-votes https://wiki.php.net/rfc/union_types but it makes his vote not logical at all
frankly the only valid reasons to down-vote something should be technical ones which matters for the PHP core itself and not "i don't understand a feature hence nobody should have it"
