Create a branch from `release/19.x` in your own fork, then cherry-pick over the changes from `main`, edit them to match the things we talked about above (and fix any merge problems). Then submit a PR that wants to merge `yourbranch` into `release/19.x`. And check the checkbox `maintainers can edit this branch` and it will help my integration!
