Yes it is.

I did; will be there in the next documentation build.

It is called from HttpExchange.

Well, I have not found yet a use case where you want this to be
completely automatic... I am open to hear though.
Yes there are idempotent requests but they are kind of rare and it's
very easy to redo them manually upon failure.

No it's not in; the old docs refer to
org.eclipse.jetty.client.api.CookieStore, which is now gone in favor
I also updated the documentation for the current master, but if you
can't wait the build, read here:
To disable cookies, or filter them, search for "disable cookie
handling" and "enable cookie filtering".

to deliver bug-free software with optimal performance and reliability,
the implementation technique must be flawless.   Victoria Livschitz
