That's new.  State tracking has never been considered important to
HTTP/1.1 and, except for caching issues, is orthogonal to the standard.
There is no reason for it not to be a separate draft.
The caching issues were handled via the Cache-control header.

Range retrieval wasn't even considered until a week before draft 00
was submitted and has only been advocated by 3 people.  Even so, we
came up with a solution in the form of 206, Content-Range, and Range.
I am not aware of any implementations of partial GET requests.

Which is the same as saying X won't achieve consensus without Y, which
is why you are wrong on this issue.  If that occurs, both X and Y get
postponed to 1.2.  There are some X's that are worth delaying the standard.

Those are *your* questions about DELETE, not the WG's.  In answer,
DELETE of a negotiable resource does mean deletion of that resource.
Proxy caches do exactly what is already defined in draft 01.
