Should BEGIN_DIR connections use optimistic data?
We could save a round trip on each directory request by using optimistic data for our begin_dir requests. It would be a pain to do it in C tor, but in Arti we'd just have to change a false
to a true
. Is that a good idea?
(By the time we are able to open a stream, we already have an authenticated circuit, so we don't need to worry about sending our request to the wrong party.)
