Ben Goodger: The problem with detecting feeds is that very many feeds are served with incorrect or overly generic Content-Types. Some are served as text/html which is clearly wrong, but others are served as application/xml or text/xml which is not incorrect, just not specific enough. We can’t attempt to parse every candidate Content-Type as a feed just to see if it is, since that would significantly impact our performance. We also can’t restrict ourselves to Feed types, since that would leave us not detecting a lot of feeds, and still be incorrect.

Added NonSpecificMediaType warning
