Excellent deep dive on QUIC's impact for scraping infrastructure. The connection migration feature is particularly underrated when working with residential proxy pools, since it lets you maintain stateful sessions across IP rotations without needing to re-establish TLS handshakes. One aspect worth noting is that QUIC's independent stream handling actually makes it more resilient to selective packet drops that some WAFs use for rate limiting. The CPU overhead trade-off you mentioned is real though; at scale, especially when you're running hundreds of concurrent scrapers, the cryptographic operations in user-space can become a bottleneck compared to kernel-optimized TCP.Makes the library support landscape pretty critical for adoption.

Yes, QUICK is definitely a game changer. Thanks for your detailed insights!
