It has a doc string, and if you look at its usage, this is all you'll
ever need.

Sorry, this name is with us for too long to rename it now.

> How is it actually used?  Is it used only in (some?) toolkits?

Look at menu-bar.el (obviously), it's used all over there.  On all the
toolkits and also in no-toolkit builds.

See above.  If you really want to see the effect of changing it
(why?), I think you will need to rebuild Emacs.
