Yes, that's exactly what it means and it's good, not bad - new() has
been doing that for years and nobody complained.

That sounds just wrong - information hiding is a basic premise of OO,
and to extend the object you shouldn't have to know the intimate details
of its implementation. In fact, in many cases you can't - such as with
internal classes. That's why we have problems with class initilization
for extending internal classes - because people are trained "you can't
just call the parent ctor, you need to verify things thoroughly first".
And that'd exactly wrong. If you know you can create an object without
parameters - new Foo() - then you should be able to extend it and call
parent::__construct() - which is supposed to do exactly the same.
Unfortunately, in PHP - unlike pretty much any other OO language - you
can not.
