Reminder: HTTP/3 support is experimental. We reserve the right to do changes like this.

CURL_HTTP_VERSION_3, introduced in curl 7.66.0, has changed with curl 7.88.0. Prior 7.88.0, CURL_HTTP_VERSION_3 implies no fallback if error; since 7.88.0, CURL_HTTP_VERSION_3 can fallback to HTTP/1 or HTTP/2.
There is a new flag CURL_HTTP_VERSION_3_ONLY that doesn't fallback. See curl/curl#10264.
