I no longer work at the company where I needed this but of course you're free to use the code as you want and continue the work.

You probably want to fork my repo and cherrypick the commit that introduced the composer v2 support because right now it's pulling other changes that are not really part of it (some workarounds for Github ratelimiting and cleanup policy support).

I also signed the CLA, maybe this will help you.

@eplightning Thanks for the signing and the tips :) And of course your work :partying_face:
I will cut the PR down, but first it would be nice to get a review from someone who can review PRs here, so I could also get that feedback in.

@func0der Do you know what the state on this is? Also would be great if you could still cut the PR down :)
