@phillip-kruger mind rebasing, the PR seems stuck for some reason

Rebased as Saturday is a quiet day :).

So I agree it looks like a neat idea. Ideally it should be based on the Accept header instead of catching the user agent but I would merge it and see if someone complains at some point.

That being said, I suggested to make the user agent test a lot stricter as the current one is very broad.
