Again, as someone who does not completely grok QUIC I am not dismissing it. I was hoping if some parameters were not exposed work would be put toward making these available through existing interfaces.

Linux network maintainers have repeatedly rejected attempts by Eric Dumazet and others to expose delack_min and other parameters to userspace. This is the kernel tyranny to which I refer.

Notably many of the people whose proposals have been shot down by linux netdev are currently working on QUIC.

Somewhat related: I do hope userspace network stacks get easier to stand up (with strict testing). It would be nice to move an attack surface like that out of the kernel.
