The simplest approach is probably to:

   - Add the bbox, srs to the GetLegendGraphic request object as a
   (the scale denominator is already an existing parameter, and width/height
   have a different meaning by spec, so I'm not sure about adding a different
   set of width/height, some consideration should be done about pros/cons of
   each choice)
   - Modify
   to count how many features match a rule own filter along with the correct
   bbox one (which has to be expressed in the source CRS, and take into
   account eventual map wrapping), if the count is zero, discard the rule

The changes need to be packaged as a pull request, following these rules:

I believe this is something that would be quite welcomed. Sponsoring wise,
we normally do
not provide quotes in public, but you can ask directly to any of these
