However that seems to be the most used form [2]. Apparently some have figured that if we have “traffic_signals:direction” there should be “stop:direction” [3] and “give_way:direction” [4] tags.

A direction tag is also used for railway signals, it's called
railway:signal=forward/backward/both. Both tags were used the first time
end of 2011 when the development of the current railway signal tagging
scheme started.
