Not necessarily, but possibly?

Not every menu item we have is "necessarily" used.  They are there
because they could be useful enough, that's all.

"Low-resolution" meaning what? 640x480?

It isn't an accident that HTML has special meta-elements devised for
mobile devices.  If browsers need that, I'm quite sure Emacs will
sooner or later need something similar as well.

Not IME, no.  Many tool-bar buttons go entirely unused.
