@mcmire I did update the README, but I had to hack the script locally because it was removing the accounts-controller from the README because of the .slice(1) here.

I didn't want to fix this in this PR, cause I'm not sure it's still required or not.

[ccharly]

I've added the DO-NOT-MERGE label, cause I've added skipLibCheck=true for tsbuild temporarily, otherwise the CI complains (something the jsx-runtime, we faced that in another PR and that might be related to some Snaps dependencies, I'll wait for more info on this before removing it from the PR)
