+One might ask why we don't just use prefilter conditions for everything, and the answer is one of slight
+subtlety: in the cases of prefilters we are knowingly exposing the user to a workspace-style UX where
+room notifications are self-contained within that workspace. Runtime filters tend to not want to affect
+visible notification counts (as it doesn't want the room header to suddenly be confusing to the user as
