this is probably not the right thing for a feature in Emacs itself.
How else do you expect this to be implemented on TTY frames? It can
either overwrite parts of the menu bar, or it could overwrite parts of
the tab bar. Something's gotta give, no?
I also don't understand why the tab bar is deemed more important than
the tool bar. Let's let users decide what they prefer. (Of course,
if there's a way to let them have the cake and eat it, too, that would
be the best.)
This feature would be most useful as a first class feature, but that
might require C changes.
IMO, usurping one more screen line from TTY frames could be
problematic, especially on terminals that display a relatively small
number of lines.
You could add another line, so that you could use the tab-bar and the
tool-bar at the same time. That would provide the most flexibility for
users, I think. They would themselves get to decide how many lines to
sacrifice. (Many users also have huge screens these days, including
vertical ones.)
That said, I don't at all object to the current implementation as an
optional feature in core, if you think it's a good idea. There's no
reason to allow perfect to be the enemy of the good.
