# HTTPS RR is technically usable with the threaded resolver, but it still uses c-ares to
# ask for the HTTPS RR record type; if DoH is in use the HTTPS record will be requested
# in addition to A and AAAA records.

# To simplify dependency management in the ebuild we'll require c-ares for HTTPS RR (for now?).
# HTTPS RR in cURL is a dependency for:
# - ECH (requires patched openssl or gnutls currently, enabled with rustls)
# - Fetching the ALPN list which should provide a better HTTP/3 experience.

# Only one default ssl / quic provider can be enabled
# The default provider needs its USE satisfied
# HTTP/3 and MultiSSL are mutually exclusive; it's not clear if MultiSSL offers any benefit at all in the modern day.

# cURL's docs and CI/CD are great resources for confirming supported versions
# particulary for fast-moving targets like HTTP/2 and TCP/2 e.g.:
# - https://github.com/curl/curl/blob/master/docs/INTERNALS.md (core dependencies + minimum versions)
# - https://github.com/curl/curl/blob/master/docs/HTTP3.md (example of a feature that moves quickly)
# - https://github.com/curl/curl/blob/master/.github/workflows/http3-linux.yml (CI/CD for TCP/2)
# However 'supported' vs 'works' are two entirely different things; be sane but
# don't be afraid to require a later version.
# ngtcp2 = https://bugs.gentoo.org/912029 - can only build with one tls backend at a time.
