I wonder what curl's defaults are wrt. accepting self-signed certs
and/or certs without a valid trust chain in the system's default
certificate store. I guess someone would have to go through all the
options and see what's necessary here.

(I guess there might be some issues here with old versions of "curl" vs.
newer versions, but at least some of the curl options have an "Added in
X.Y.Z" which I could be used to guide decisions here.)
