I know I'm a bit late to this thread, but I find the above worrying,
depending on the "depending".

If the defcustom has three values "Always-y-or-n", "Always-yes-or-no",
"depends-on-the-particular-invocation", I'm fine.  With just the first
two alternatives, I wouldn't like it.

i.e. each formerly yes-or-no-p call would have to be something like

    (y-or-n-p "Really? " t)

.

I'm wondering whether coalescing these two function is more trouble than
it's worth.
