As the co-author of the conveying proposal, I'd like to offer an 
alternative here. The proposal already mentioned the conveying:lanes 
syntax as a possibility for mapping parallel escalators, and escalators 
parallel to regular steps.

I think that doing it that way has significant benefits for rendering 
(i.e. avoid the inevitable overlapping ways and gaps), and the approach 
might be extended to other highway=step attributes where the need arises.
