Cacheability; MKCOL idempotent?

While looking into BugZilla issue 80 ("Specify idempotence and safeness 
for all new methods", 
<http://ietf.cse.ucsc.edu:8080/bugzilla/show_bug.cgi?id=80>), I noticed 
that RFC2518 says that MKCOL's results aren't cacheable because it's not 
idempotent (see 

I think that's incorrect, because similar to PUT, repeating the same 
MKCOL request multiple times will cause the server to have the same 
state afterwards (just like PUT, but unlike POST).

So I fixed that, but wonder: should this affect what we say about the 
cacheability of MKCOL results? Are we still saying "MUST NOT be cached"?

As a matter of fact, should we rethink that for all methods? We 
currently say that PROPFIND results SHOULD NOT be cached 
Is there any good reason for it? Should the fact that real-world WebDAV 
clients *do* cache PROPFIND results tell us something? :-)

Feedback appreciated,
