Frame zooming does that.

Frame zooming does not do that.

(And I, for one, don't think I would want that.  Maybe
it could be an optional behavior, if there's really a
use case for it.)

Frame zooming does not do that.

Likewise, it doesn't zoom scroll bar width.  But it would
certainly be possible to zoom such things (and tooltips).
That should likely be optional - be able to specify for
_each_ such non-font thing whether to zoom it when zooming
a frame.

Frame zooming does not do that.

There are likely many things in Emacs that people
learn and forget, if they don't use them often.
And not just Emacs.  I'm sure you're used to that,
as a teacher.

Frame zooming does that.

That wouldn't let you show parts of the same buffer
in different windows with text show at different
sizes.
