You'll need (maybe?) a Safari checker also? I see FF1.5+ and Opera 8+. Some things that people do rely on Opera 9+; some things rely on FF3+. So one could imagine a finer-grained checker which, instead of returning true or false, returns something which is SMIL-sensitive or displacement-filter-sensitive (I think you'd handle those with try and catch instead though).
The intent of the developer could enter into the equation as well: if it's IE then would we rather render in VML or alert to the existence of a plugin? If there is no SMIL would we rather alert to the existence of other browsers or to Doug Schepers SMIL -- JavaScript stuff? I don't think most of my concerns would be relevant to many people, since you are working at a more global level with what you suggest. But the Safari thing probably would be since it likely brings its own personality into the equation (having not been able to test Safari very much -- I'm hoping I change this soon.)
