I don't have a problem with that, or with similar non-visual POIs like concert halls, theatres, etc. They're of interest to a relatively large group of people.

I take a different view to them: if it is useful to more than a very tiny minority of people then it can and should be mapped. "Useful" includes using it as a landmark for navigation or to confirm that you really are where you think you are (so inscriptions on plaques are useful because there could be more than one plaque in the area where you are and the one you're stood in front may not be the one you think it is). "Useful" includes people wanting to find a POI of that particular type, or finding a specific POI. "Useful" includes opening hours so you don't waste time going somewhere that isn't open that day. How many people care if a church clock escapement uses a pendulum or is electronic? How many people care if a church has four bells or five? How many people care if the church bells are rung by tugging on ropes or by a carillon? The answer to that last question is not many, unless it performs frequently and regularly so they could plan an excursion to hear it. I don't think tagging carillons in churches is important at this time. There are still plenty of things to map that are of far more interest to far more people. But if somebody thinks it is really important I won't oppose it, because "any tag you like" means there's no way for any of us to stop it happening, the best we can hope for is to guide the choice of tags to be sensible. So you write a proposal and I won't vote against it unless I think the key and/or value you propose is flawed. I might even vote for it. But I think it will be applicable to such a small number of POIs and be of interest to such a tiny fraction of mappers and users that it's not worth the effort. -- Paul
