curl the next few years - perhaps

Roadmap of things Daniel Stenberg wants to work on next. It is intended to serve as a guideline for others for information, feedback and possible participation.

"Complete" the HTTP/3 support

curl has experimental support for HTTP/3 since a good while back. There are some functionality missing and once the final specs are published we want to eventually remove the "experimental" label from this functionality.

HTTPS DNS records

As a DNS version of alt-svc and also a pre-requisite for ECH (see below).

See: https://datatracker.ietf.org/doc/html/draft-ietf-dnsop-svcb-https-02

ECH (Encrypted Client Hello - formerly known as ESNI)

See Daniel's post on Support of Encrypted SNI on the mailing list.

Initial work exists in https://github.com/curl/curl/pull/4011
