Will there be support for http3?

I’m using this conf and it works fine:

server {
        listen      203.0.113.1:443 quic reuseport;
        listen      203.0.113.1:443 ssl;
        server_name example.net www.example.net;
        root        /home/user/web/example.net/public_html;
        index       index.php index.html index.htm;
        access_log  /var/log/nginx/domains/example.net.log combined;
        access_log  /var/log/nginx/domains/example.net.bytes bytes;
        error_log   /var/log/nginx/domains/example.net.error.log error;

        ssl_certificate     /home/user/conf/web/example.net/ssl/example.net.pem;
        ssl_certificate_key /home/user/conf/web/example.net/ssl/example.net.key;
        ssl_stapling        on;
        ssl_stapling_verify on;

        # TLS 1.3 0-RTT anti-replay
        if ($anti_replay = 307) { return 307 https://$host$request_uri; }
        if ($anti_replay = 425) { return 425; }
        add_header Alt-Svc 'h3=":$server_port"; ma=86400';
        include /home/user/conf/web/example.net/nginx.hsts.conf*;

Remember quic reuseport only in one server block, for the other domains, only quic
