Statement of intent regarding TLS server name identification (SNI)

[Drew DeVault]

Hiya! On behalf of the gmnisrv server software
(https://git.sr.ht/~sircmpwn/gmnisrv), I'm writing to inform client
authors that our intention is to *require* clients to enable server name
identification (SNI) when making TLS connections. We will drop
connections which do not provide SNI.

It's pretty easy to add to your cilent, so please double check that
yours does it! My server, gemini://drewdevault.com, is running gmnisrv
with this requirement enabled if you want something to test against.
