CA verification and client-side certificate verification
I don't know if you would consider this to be featuritis or not but I would really like to see support for CA and client-side certificate verification and validation. I am looking forward to the continuing maturation of httpd. It is light years ahead of apache and nginx in terms of rapid deployment and sane configuration.
Maybe reyk would really consider this feature because two years ago he mentioned to think about it again if libtls would integrate SNI (https://github.com/reyk/httpd/issues/23). After @jsing added it (http://undeadly.org/cgi?action=article&sid=20160823100144) now, there could be hope...
By "client-side certificate verification and validation" do you mean the same thing as client-certificate authentication? If so I would like to see that feature also.
