@compositor yes - getting the active window or class name is extremely trivial w/ X11 & apps &/or scripts written to help w/ all sorts of use cases & accessibility needs sometimes need that awareness.

I know the response has been for DEs to all individually re-implement this feature however they see fit - but that’s a lot of fragmentation & I’ve yet to see gnome really solidify how they’ll expose it long term.
