"SPC vs SPC SPC" lets you eat your cake and have it too, because while
it shows the difference, your brain will happily disregard it, so noone
ever felt the need to provide a command to switch between "show the
diff" and "hide the diff".

So, yes, it's about "requiring".

Yes, in the general case, there's probably no way to avoid the need to
distinguish between "show markup" and "hide markup".  But some markup
(such as the SPC vs SPC SPC convention) is sufficiently lightweight that
you don't need to have those two states.
