We'll have to look very carefully about code that makes use of
IsCertificateError() to be sure your new error is treated accordingly. Or
perhaps it'll be best to put it in a different place. In some sense, it's not a
"Certificate Error" so much as it is an "Alternate Service Error (because of
certs)".  I recommend moving, so we don't have to reason about this.
