This particular restriction is mostly arbitrary anyway because `this` and `super` accept arbitrary expressions (including static method calls), so in most cases

This particular restriction is mostly arbitrary anyway because `this` and `super` accept arbitrary expressions (including static method calls), so in most cases it's possible to do this, just with much worse syntax. Technically, this does introduce new functionality when extending a class, specifically it's possible to choose a constructor to overload depending on arguments, but in most cases there is usually one constructor that all other constructors use.
