More or less, yes.  But I like to focus on "identifying resources"
rather than "encoding queries".  Think of a query as identifying
something.  For example, this query identifies all resources that
Google knows about that includes your name.

Yes!!  This is a Good Thing.

I think the creation of new URIs is a wonderful side effect (no pun
intended 8-) of having a single "retrieve" method.  Looking at
PROPFIND again, if the "properties for a resource" were identified by a
separate URI rather than retrieved via a non-GET method, then we could
make assertions about the properties, cache them, use XSLT on them, etc.
All the goodies you get by having a URI.

The "U" in URI stands for "uniform" (previously "universal"), which
means that a URI identifies the same "thing" in all contexts.  Having
a single method meaning "show we what you are"/"resolve"/etc.. helps
ensure that uniformity/universality is maintained.
