c is as good as a shortcut, of course.
Regarding the discussion from 2016 (and the main point "adding boot parameters
to grub is not that easy; needs to be discussed with grub people):
For people which are able to see, what they write, it is probably possible
to add additionally parameters to a commandline, even if a bit uncomfortable;
but for people being nearly blind at that step, it's de-facto not possible!
That's why a shortcut for those scenario should be added.
And following that argumentation, it should still be possible to argument
why we do NOT add other shortcuts just for comfort.

As written above: syslinux should get a shortcut too IMO.
