This discussion highlights the challenges surrounding the adoption and implementation of HTTP/3 and QUIC across various programming languages and platforms. Despite claims of rapid migration of web traffic to HTTP/3, many major programming languages lack standard library support for these technologies, causing hesitation among development teams to integrate them due to concerns about stability and debugging complexities. While some libraries (like .NET) show promising support, the overall ecosystem is still developing, affecting choices for developers, especially when optimizing for more immediate product deliverables. Several comments suggest that while HTTP/3 brings potential improvements, its advantages over HTTP/2 may not be critical for smaller-scale projects, resembling issues seen with the slow uptake of IPv6. There's a growing sentiment that lack of HTTP/3 support may lead to user-experience hindrances in the future, possibly segregating legacy clients from modern web services.
