[Talk-GB] Entrances with staircases

[Michal Vinarek]

Hello all,
how would you map entrances with staircases like these? 
https://www.bing.com/maps?cp=55.876434~-4.293361&lvl=17&dir=127.546&style=x&v=2&sV=1
I'd assume entrance=staircase is used rather to denote an entrance 
leading to an internal staircase 
(https://wiki.openstreetmap.org/wiki/Tag:entrance%3Dstaircase), and 
other than that there does not seem to be a tag that I could apply 
straight to the node to say that this entrance is only accessible via 
staircase.
Would it, in this case, make sense to map each of the staircases as a 
line (highway=stairs) from the road to the entrance node itself? This 
approach seems fairly messy with a lot of entrances close to each other 
though, so I am wondering what the best way to map these would be and if 
someone has found a more suitable approach?

Cheers.
