RFC2119 is just formalising and explaining English for
non native speakers in this respect.

"Generally accepted" is correctly mapped to "should".

But there are others which are really a must:

"Where ways intersect at the same altitude, the two ways must share a
node (for example, a road junction)"

"You must explicitly specify the unit if it is not in metric tonnes."

So the English language is used appropriate in the Wiki.

It does not even talk about non divided ways beeing mapped as seperated
ways. So if lawyering correctly this whole discussion is moot because i
dont think there is a place in wiki talking about ways without a divide
to be mapped as 2 ways.
