These features weren't considered to be usable enough to be merged 
into the mainline branch, hence were removed before the merge.

For QUIC in the stream module, see this message, which provides 
detailed explanation:

https://mailman.nginx.org/pipermail/nginx/2023-April/CZ5L6KMLLZNDP2R6TGAX5MN4VLQA3U3R.html

For HTTP/3 Server Push, the main reason is that Server Push is not 
generally usable, and, in particular, not supported by browsers 
(notably, removed from Chrome, see 
https://developer.chrome.com/blog/removing-push/).  Removing 
HTTP/2 Server Push support is also planned sometime during nginx 1.25.x 
development cycle.
