Once your PR is ready for review, check one last time that all required checks (other than "Required review") appearing at the bottom of this PR are passing or skipped.
Then, add the "[Status] Needs Team Review" label and ask someone from your team review the code. Once reviewed, it can then be merged.

We probably can add it, if we do it might start making Jetpack rank as a “translations” plugin though (for front end of the site, like https://wordpress.org/plugins/weglot/ )

@jeherve I've added in a bullet on translations (the copy for this is part of the launch materials - i.e. I've not just made it up)
