Comment (by dcf):

 Heads up, upstream utls fixed a distinguishability bug recently. A second
 ClientHello (which the client sends after the server sends a
 HelloRetryRequest) was not being camouflaged correctly. I confirmed that
 the bug existed with HelloChrome_70 against ajax.aspnetcdn.com, but I
 haven't personally tested yet that the fix actually fixes it. When I do,
 I'll update the branch.
