What is a "caching keyserver" in this context?
What purpose would it serve?

A WKD request would only be served by the TLS certificate of the 
webserver of the original domain. This cannot be cached, otherwise the check 
would not be working.

Also, a third party server would not know the email address to ask for.
(Unless given by some application.) So why would this application prefer the 
third party server when it could ask the real WKD server?
