No, that's not the issue.  It's not about "which window (the
selected-window or the returned window) is the new one" it's "which
window (the top one or the bottom one)".

And the issue is not "tell me which it is" but "I want to control which
one it should be".

No, here's the scenario: you have a dedicated window, and you want to
create a new window above that one: split-window won't work because it
will always create the new window below.
