I agree with most of what you said, but mapping CRUD directly onto the verbs is perhaps a little simplistic. See http://jcalcote.wordpress.com/2008/10/16/put-or-post-the-res... for a discussion on it. The very short version is that idempotency is important, POST must be used for non-idempotent updates, and there is no reason PUT can't be used to create if you know the ID of the resource.

HTTP PATCH was created due to this problem, though I've not run across an API using it yet.

The discussion here around the article I linked was my first introduction to PATCH. I would really like to see it implemented in Pyramid so my site can take advantage of it.
