Yes, on/off would be fine.

I don't see why not.

I think %R and %r have been preempted for the spell correction prompt
(see SPROMPT in the manual, could probably stand to have a mention
added in the section with the rest of the prompt expansions).

Perhaps the way around this is to use %A/%a for "attribute" the way
%F/%f are use for foreground color.  Thus %A{03} would be italic
(where supported), %A{07} would be reverse, etc.  Your call whether to
define some counterpart of the ansi_colours array in prompt.c that
supplies symbolic names; Functions/Misc/colors has the ECMA-48 table.
