Warning for emergency exit not in route or stop_areas (tagging issue?)

[double-a]

Essentially 2 warnings for the same node:
Found 1 entrances not used in routes or stop_areas: n315269742
1 subway entrances are not in stop_area relations: n315269742
The node is just an emergency exit far away from the next stop, thus it is not part of a stop_area.
Maybe one could add it to the route, but I do not think that there is a matching role for this.

Anything wrong with the tagging of the node? (access=emergency, entrance=exit, railway=subway_entrance)

Or should the check ignore such nodes?

As I can see, Tag:railway=subway_entrance and Key:access pages don't consider railway=subway_entrance + entrance=exit + access=emergency tagging as correct for such exits. Maybe exit=emergency is more suitable, but Key:exit only mentions it without assertion of approvement status.
