From a typesystem point of view it would be perfectly leagal to change the typehint in a derived class as long as that respects is-a relation with the parent. Since the explanation is a bit complex, not what most people expect we live with the simple disagreement. And since most languages do not respect this correct or not at all anyway there is obviously no real common usecase for it. So PHP can live without that too (imo).
