Enabling this certainly makes sense. It's called Path MTU Discovery though.

Isn't it enabled by default?

Windows has more chances of getting this error and a similar bug was fixed in the opposite direction by @marten-seemann a couple of years ago for go version. IMHO it makes more sense to make it configurable to cover more cases.

😄 you are right. It is the default since May 6th this year. quinn-rs/quinn#1547

I don't have an opinion on this. Also I would rather have that decision be made in the default implementation of quinn rather than libp2p.
