When this draft was presented at the October interim, it was presented in
the context of solving the problem of providing a safe (and idempotent)
HTTP method that has a request body, i.e. a safe POST or a GET with a body.
That problem (i.e. specifying such an HTTP method) is what I'm interested
in solving, not bringing WebDAV's SEARCH semantics to HTTP.

A question for the working group: in this Call for Adoption, are we
considering adopting a general-purpose method that is safe and has a
request body, or are we considering adopting work on the specific
search/query semantics that this draft intends to cover?

If the former, I support that goal, and this draft could be a starting
point. If the latter, I do not support adopting this draft. It also appears
that the draft does not succeed in meeting that goal. The draft includes a
list of 4 bullet points in the introduction of problems using the GET
method. The first two points concern the semantics, but they are not solved
by the SEARCH method presented in the draft. The last two points are
addressed by the SEARCH method, but they are not specific to search/query
semantics and would be solved just as well by a general-purpose method.
