I think not. I see many (non-Org) ASCII documents that distinguish a
notional em dash from en dash by different number of hyphens, as in your
first list.

“Consistent with ASCII”? ASCII has neither en dash nor em dash, so it's
not ASCII that you're wanting to be consistent with. You're referring to
conventions that attempt to preserve Unicode characters in ASCII.
