If this plays well with the language and standard library features I am ok with it. It
doesn't remove all the additional effort I mentioned but it will prevent the unnecessary
interfacing/casting. As soon as user code is be rebased to ssize/C++20 and qsizetype
everything is consistent which is the most important thing. And I suppose other libraries
will follow the coming standard soon.

BTW Are there plans/roadmaps regarding C++20 support?
