#75: 421 Status with Alt-Svc Header

<https://github.com/httpwg/http-extensions/issues/75>

The spec current says:

"""
A 421 (Misdirected Request) response may carry an Alt-Svc header field.
"""

I think Mike is suggesting a change to something like:

"""
A 421 (Misdirected Request) response MUST NOT carry an Alt-Svc header field, and clients MUST ignore any Alt-Svc header field in one.
"""

Another approach would be to caution implementations that loops are possible if an Alt-Svc on a 421 is followed, and to exercise caution (including loop detection with fallback to origin).

Thoughts?
