I'm one of the engineers working on QUIC projects at Cloudflare. This response from jgrahamc just came to my attention. His comments are based on a discussion I had with him about our first QUIC project and then additionally what I knew of quinn. I described how quinn was arranged and that it provided an interface that was oriented towards the tokio IO library. What I seem to have failed to communicate was the IO specific interfaces were not the only interfaces provided by quinn, and that more abstract interfaces do exist. This mistaken impression seems to have been bundled with the multitude of reasons that we did not choose various other QUIC implementations. I'm sorry that this this mischaracterisation was made against your work, and hope anyone reading this thread does not take away the same impression.
