[mxinden]

Description

Combining these is tricky. I think we should have an example on how to combine them.

Motivation

Helps users getting started.

Requirements

Are you planning to do it yourself in a pull request?

No

Although i do need to test quic with relay again, this should be pretty easy to do assuming the way I been doing it is correct. Would be helpful for anybody getting familiar with it and maybe even go as far as testing it with dcutr

Note that dcutr together with QUIC is not yet supported. See "long term": #2883

Thanks for that. That does explain alot in earlier testing

@thomaseizinger I remember you being opposed to adding QUIC to development_transport. What do you think of a transport-combination-example instead?

I am guessing you are talking about #3060 (comment)?

I am okay if we add it in the meantime, long-term, the composing must be so easy that we don't need an example for every transport.
