For those not following the release notes `"editor.bracketPairColorization.enabled": true` is a new option in VSCode (since September's release) after the team saw how common extensions like Indent Rainbow and Bracket Pair Colorizer 2 were and how many complaints were out there about how slow they were, so they decided to add it as a built in feature that can reuse the same processes as the core indent guides. Also a lot of interesting work went into optimizing the algorithms at work: https://code.visualstudio.com/blogs/2021/09/29/bracket-pair-...
An interesting case of the team watching the extensions ecosystem for ideas to make the core product better.
