It does that "as well as it can".

Well, if we want to go pedantic, then "the screen size" was never
formally defined.  Any reasonable definition must keep the task bar
visible, so I'd actually argue that the text is reasonably accurate.

People can use your frame-cmds.el code, until someone figures out how
to do all that on the C level and in the framework of how Emacs reacts
to changes of frame parameters.
