The proposed new rules for calling this() and super() aren't so foreign. It seems to be almost the same rules as for assigning final instance variables (e.g. class Foo { final int bar; } }), where you must definitely assign every final field exactly once in the constructor, not more, not less. Still, after I experienced the constructor-less paradigm in Rust, where you only can only construct structs entirely all at once, and every "constructor" is just a static factory function, it's harder to justify the traditional OOP paradigm in Java, C++, etc.
