Regarding fairings, it seems a missing "middleware" case might be the sorts of things that cause redirects on entry (e.g. redirect routes with/without trailing slashes to the latter as a super trivial example). Is that something you'd expect to support in some way? I think that's something that doesn't feel like it maps either to guards or fairings well at the moment.
I did see where you mentioned your dislike of rails/sinatra/... style blunt force middleware, fwiw.
