Contextual legend is a non-standard feature, not sure how QGIS could
rely on capability info to figure out. Moreover the user might want
it enabled only for some of the layers. The per-layer option was explicitly
requested by the funding party (Regione Toscana).

So I would see a per-server option to determine a per-layer default
(overridable) and eventually an "autodetect" choice for that option in
case there's a likely-to-work way to do that.
