No, we don't NEED. But today, as Ben Schwartz and Dave Lawrence
noticed, we have a much worse situation: clients and servers can choose
and, as a result, they may be unable to interoperate. So, mandating
GET *or* POST *or* both is necessary, to solve this interoperability
problem.

Now, regarding your question: experience from the hackathon seems to
indicate that supporting both GET and POST is very little work.
