I can see this used for the edit boxen and text mesasge dialogs which
would be quite similar.

Also the templating seems quite flexible and versatile.

However, can't this be done with a shell function?

Both the grub.d scripts and grub.cfg can define a function with a few
parameters to achieve pretty much the same results.

IIRC one of the sample menu.cfg files defined functions as part of
grub configuration so we do not need another facility for this.

It won't. You cannot know how much space the "most space" is.

This is an interesting addition but I'm not sure where this would be used.

Normally one terminal is enough so you can just open it fullscreen and
close it when you want to do something else.
