Unless you're using QUIC as some kind of datacenter-to-datacenter protocol (basically as SCTP on steroids with TLS), I don't think QUIC in the datacenter makes much sense at all.
As very few server administrators bother turning on features like MPTCP, QUIC has an advantage on mobile phones with moderate to bad reception. That's not a huge issue for me most of the time, but billions of people are using mobile phones as their only access to the internet, especially in developing countries that are practically skipping widespread copper and fiber infrastructure and moving directly to 5G instead. Any service those people are using should probably consider implementing QUIC, and if they use it, they'd benefit from an in-kernel server.
All the data center operators can stick to (MP)TCP, the telco people can stick to SCTP, but the consumer facing side of the internet would do well to keep QUIC as an option.

For what it's worth: Romania, one of the piss poorest countries of Europe, has a perfectly fine mobile phone network, and even outback small villages have XGPON fiber rollouts everywhere. Germany? As soon as you cross into the country from Austria, your phone signal instantly drops, barely any decent coverage outside of the cities. And forget about PON, much less GPON or even XGPON.
Germany should be considered a developing country when it comes to expectations around telecommunication.
