Impressive work. @seunlanlege Are there still any pending issues with this PR? If not, let's rebase and merge.

@svyatonik Could you please check if there are any potential issues with the light client changes?

[bkchr]

Same. Please bring it back.

Polkadot companion PR is green 🎊 🥳

[bkchr]

Please make sure your polkadot changes work with cumulus.

[gnunicorn]

Thanks, this is a big step forwards. Let's please restrict the actual requirements a bit and make sure that we have a patch pending for cumulus if necessary.
