By "all properties" I hope you mean "all construct properties" or we
have a serious efficiency issue. ;-)

Why are construct properties different from regular properties in this
respect? i.e. why are we setting them to their default value at all?

Normal properties have their defaults filled in _init(), construct
properties could work the same way.
