Yes, it was me who added that key to the wiki page, because it was mentioned in one of our Hungarian documents some years ago and also I wanted to use it.
I admit to my error in not noticing the latest proposals earlier. I've just recently joined this list and I've specifically asked this here in order to correct my error. I volunteer to fix previous tags with whatever we come up with as a replacement. In my defense, do note that the proposal process is only one way to start using new tags: https://wiki.openstreetmap.org/wiki/Any_tags_you_like https://wiki.openstreetmap.org/wiki/Just_Map https://wiki.openstreetmap.org/wiki/Good_Practice#Document_your_custom-tags https://wiki.openstreetmap.org/wiki/User:Joto/How_to_invent_tags https://wiki.openstreetmap.org/wiki/Proposal_process https://wiki.openstreetmap.org/wiki/New_Features Of course, I agree that if a proposal process is underway in a specific area, it is much more productive to pool our focus to the given process instead of doing ad hoc extensions in parallel. I would definitely tag this property, because it is possible to break a hydrant with the huge keys that are used to open it if it is rusty and you are forcing it in the wrong direction. In Hungary, I've seen both opening directions fairly often, though I don't have exact stats as of now. Official fire fighters here have their own (closed) database of hydrant here and the vehicles also store a great amount of water so OSM is not useful to them in this aspect. Pressure is not indicated on plates, only diameter, but as that is not correlated reliable with pressure, they usually do not decide based on that, so this property is not useful either. I think that opening direction is the more useful property of the two, though the local community maps all data from the plates. I don't have strong preferences for the exact key, but in the value part, I would like to see something that mirrors the plate that is depicting either clockwise or counterclockwise. I don't have a strong preference regarding abbreviation, although I guess it would be more accessible when typed in fully.
