Agreed but the wiki for beach says when applied to beaches it specifically means supervised by a lifeguard, when applied to other features yes it's unrelated to lifeguards. This is how I've been using the tag, I think that's okay as the default. It is common for beaches to have supervision that's not a lifeguard? I'm all ears for a proposal for finer grain tagging, but until them I'd encourage people to keep mapping per the wiki using supervised on beaches with lifeguards.

Just like how a single road is split up to tag different maxspeed, surface, lanes etc.
