Ok, but where does this question came from? Leisure is an open tag... Is every pair tag=value having his own discussion and proposal? I'm asking because most of them don't have it. I needed something to mark this kind of places for our new project for polish lifeguard volunteer service, I didn't found anything, so after a consultation with local community I created it, made wiki and started using it. Proof that it was needed is in data - it's in use (>250 points) and other users made translations of wiki in other languages. This project now is in hold but I'm sure we'll continue it... even if not - as You see - tag is useful, (also, but not only) for other users of our software and maps based on OSM such as polish firefighters which are also doing some job related with water-rescue.--Jendrusk (talk) 07:14, 20 May 2016 (UTC)
How is a leisure=swimming_area different than any place that has water? There is always a potential for swimming. Seems ambiguous and hard to verify. What if that swimming place becomes unpopular and many people stop swimming there... does that place need to have a new tag?
Of course, but I'm using it to mark named (!!!) places on open air where you can safely swim (cause: there is a lifeguard (and/or) good quality of water (and/or) deep enough (and/or) without any danger objects under surface etc. So as you see it's something different then just 'any place that have water'. Also not every place near water is good for swimming... Of course I can get back my data and keep it locally and serve only for users of my aplication but I think spirit of OSM is to share it, and that's what I'm doing now...--Jendrusk (talk) 13:00, 20 August 2016 (UTC)
Did not see the term "named places" in the original description. Could leisure=beach ; name=* not work for you? Anyway, I suppose you can use whatever tags that you want, but if you are going to define usage in this wiki, then you should welcome discussion regarding the idea.

Ok, maybe too aggressive - excuse me... In Poland beach is translated as 'plaża' which means a piece of seashore (!sea-most) with some sand. Swimming_area is quite similar with leisure=beach, but only quite - 4eg. beach called 'Jelitkowo' in Gdańsk is about 3 km of seashore but only abt 500m of it is a swimming area. This means that in this place someone (lifeguard) is responsible for your safety in water. In other parts you are not allowed to swimm... Of course you can swim there but if you'll get hurt it's only your fault. Maybe in other parts of world things and meaning of word 'beach' are different... Also you can have a swimming_area at a river or lake which noone in Poland call a beach (no sand and not over the sea), but there is a place where you're allowed to swimm and a lifeguard is responsible for your safety. Ergo: in Poland part of most beaches is a swimming area, but not every swimming area is a beach - that's why I'm using different tags :) --Jendrusk (talk) 1:00, 21 August 2016 (UTC)
