I can see why they rewrote QUIC in Rust and for use in userspace, though going the in-house approach would warrant keeping an eye on the relevant kernel commits like a hawk to avoid missing bug fixes like these. These in-house protocols tend to have less eyeballs than the kernel.
I found it interesting that Cloudflare is not yet using BBR [0]. I wonder if they're testing it in-house at least. CUBIC's recovery in this day and age, and especially in datacenters with large pipes, seems so slooow to me. Almost two full seconds with no loss whatsoever till achieving BDP again.
