That cipher list is the only one I've found that allows for HTTP/2,
compatibility with older clients, and hitting an A+ on all
at once. Everything I've done tinkering on my own could only hit two of
those three goals. 

Bozohttpd doesn't support HTTP/2, so that point isn't achievable. But
that cipher list is still works great and that's why I recommend it to

I've always assumed that having a good enough OpenSSL version and
simply enabling the proper cipher would turn on Perfect Forward
Secrecy; however I wouldn't be surprised to be proven wrong. Code may
still need to be modified.

Forward Secrecy only guards against your private key being discovered.
Your data will still be secure without it, assuming you follow safe
practices with the key.

Getting PFS enabled is a worthwhile thing to do. However I believe
if bozohttpd is good enough for what you are doing, you will be safe
enough with a mere A-minus rating. If you really need an A or A-plus,
there's always nginx.
