Since the original implementation and discussion, I had a lot more time to
discuss this proposal with Roger (who was heavily in favor of it), think
about it, and work on other HTTP-based protocols.
Thus, I am now in favor of a solution. It is good that you laid out the
implementation details as well.

Well, that's what they actually do.

I think there were pretty strong objections to layers for XML-RPC and all
other non-browser HTTP requests.

I think I was against anything typing non-browser related.

This is good.

This would not fulfill the use case that Fred brought up in his response to
the proposal. I really like his points and his historical considerations.
I think, it would be ideal to have one way to specify the request type, maybe
through ++type++. If, for legacy reasons, ++skin++ is easier to use, then
that's fine with me too.
Let's widen our considerations to JSON and REST as well.
What do others think?

Right, this is very important. The same rule should apply for IBrowserRequest;
see the other discussion thread of this mail.
