The problem is not the "Abort" itself, but more precisely "user-error",
rather than Abort. I suppose that depends on how many packages on ELPA check
on "capture user-error".

It is not so much about imposing it, but it would make the whole thing cleaner
as you described.

I see. Still, I am not against signaling an abort.
