Repeatedly we're seeing questions on when http/3 will be implemented. http/3 is available in the experimental branch of Nginx, called "main line". This is not a branch that is "stable". Plesk only offers stable software versions for the utmost reliability you can get as reliability is much more important than speed. A fast website is of no use if its webserver crashes or the protocol doesn't work as expected in all cases. Plesk does not offer experimental features. The stable version of Nginx that supports http/3 is expected to become available in April 2024. This is when it makes sense for Plesk to also offer http/3.
From articles that foster the hype about http/3, it sounds as if it can increase a website's speed incredibly much. On average, on real website tests by several reknown sources, the acceleration has been seen at around 0.2 to 0.3 s/page, typically around 12 % improvement compared to http/2, but it depends on the actual website content. Most website owners will be able to increase the speed of their sites dramatically more by reviewing the scripts/plugins/themes they use, because most issues of slow websites are caused by bad software.
If you comment here that http/3 is a "critical feature" (as we've seen many such comments), please also argue, why this is such a critical feature.
