The question is whether you consider it a problem if ALPN can
negotiate protocols that others cannot.  Or, if you consider upgrade
to be the only place where a mechanism of this nature exists, that
those "others" might be required to perform some escaping, with all
the bugs that entails.

We're defining our strings in the ASCII range, so I didn't see a big
problem with the extra flexibility.
