So it appears the letter designations are stand-ins for the name or the ref or
more specifically the name as it appears on signage. It could be the name of
a city for example. I am having trouble relating it to width, but I think the
width:lanes:start/end formulation could cover it.

My first take:
lanes:forward/backward might possibly be redundant.
I think of it as a suicide lane, and it might confuse JOSM's "Enhanced lane
and road attributes" even more than it does me. Well there is at least one
way to find out.
