libp2p v3 release issue

[achingbrain]

This is a tracking issue for items that will cause v3 of libp2p to be released. The idea is to only do this once per year - v2 shipped in early September 2024 so we are approaching a reasonable window to release v3.

This list is currently non-exhaustive and may grow and/or shrink over time.
