It sounds like a safer solution would be to get Apple to either make this
method public and make a promise of sorts that they’ll keep it working, or to
get them to not even call it on your class (I didn't quite get the det

sounds like a better approach than trying to modify (or replace) the userInfo

Apple ever decides to put stuff in the userInfo after all..

looking up the UTI from your Info.plist instead of from Launch Services
