Assuming it's supported upstream, I suspect this would break people who
are using GSSAPI (or Digest) authentication for their proxy.  This would
be a logical thing to do where Kerberos is used.

It might be worth checking exactly which bits cause problems for you;
perhaps your proxy might be misconfigured to suggest a type that it
doesn't support.

This looks like the documentation for PHP.  The libcurl documentation[0]
doesn't mention a limitation.
