The incentive is that "X works on Firefox but not Chrome", (or vice versa,
X could be Google, Facebook, whatever.

This kind of failure makes the client look bad, it makes the site look bad.
Both are incented to fix it (though the site is more incented to fix it,
generally), but fixing it often requires action on the part of the user.
What if the user doesn't have permissions to change the client, or simply
can't be bothered to do so?

I don't want to be in a situation where sites don't deploy HTTP/2 because
of buggy clients.
Certainly there would be clients which would not implement this, or do it
in a broken way.
