We're using the WM_CLASS of the window itself.

That just seems to be talking about how the session manager proxy
identifies applications without a WM_WINDOW_ROLE property.

Slightly more relevant is the WM_HINTS window_group, for which it is
stated that the group leader holds the "properties" for the group.[2] But
I'm not sure whether WM_CLASS is one of those "properties", or if
"properties" is just referring to the rest of WM_HINTS.

Having the group leader or client leader override the WM_CLASS would
mean that you couldn't specify different resources for different types
of windows in the group, which would reduce the utility of resources.
