> Every app has to implement it itself No? I'll just link against one of the cross platform libraries that implements it, the same as for any other networking protocol. (Ex https://github.com/microsoft/msquic https://github.com/microsoft/msquic) Also see: https://github.com/quicwg/base-drafts/wiki/Implementations https://github.com/quicwg/base-drafts/wiki/Implementations > same as for TLS, making fewer apps implement it without a lot of extra work ... do you not just link against a relevant networking library at this point? If not, why?!
