Is stating a max zoom actually necessary for a WMS server? If this is a JOSM requirement we need to have a look at all WMS defs.

I don't know. With this layer and without maxzoom I see grey tiles in JOSM at z>18. While e.g. VoGIS: Echtfarbenbild 2012 (12cm) works fine in JOSM even without maxzoom.

Max zoom is at least useful to iD - it tells the code at which zoom to stop requesting images and switch to overzooming. (e.g. there is no reason to ask the server for 4 z19 tiles, when we know that the z18 tile we already have loaded is as good as it gets).

I know iD don't support wms yet, but even if we did, fetching raster tiles would work the same way.

@bhousel I might be mistaken but IMHO WMS servers return which scales they support so this might simply be a misconfiguration of the WMS server in question.

I'm thinking of the very simplest case where iD would send bounding box requests to EPSG:3857 supporting servers, per openstreetmap/iD#1141 (comment)

Specifying a maxZoom would help iD here. I'm not planning to do GetCapabilities calls anytime soon.
