It seems like we have weak consensus to go with C where the server must support 
all three formats, and the client can use either one. This approach addresses 
most of the concerns around client complexity / size. Only one person strongly 
objected to C (without an explanation that can be addressed). Summing up the 
results was hard because many people had no strong preference between A and B 
but with each of the three options received about a third of the votes.

My guess is that if we held another vote asking if the spec should only support 
form-encoded or all three - all three will get most of the votes (and same if 
we made JSON the only option or all three). This is why C is really the only 
way to move forward at this point. We can revisit this later if implementation 
experience shows supporting all three in this manner is a problem.

I am going to add this to the specification as a point of reference for future 
discussions.

Weak consensus to support both request parameters and HTTP Basic authentication 
(with other schemes as optional). I will add a new section to the draft 
allowing replacing the parameters with an HTTP authentication header. The flows 
text will remain the same.
