If all of the engineers on the team are quasi-literate, then sure, the policy is defensible to use copywriters to vet messages. Everyone makes mistakes, though

If all of the engineers on the team are quasi-literate, then sure, the policy is defensible to use copywriters to vet messages. Everyone makes mistakes, though. A much better policy, just in general, would have been to require all commits be reviewed by someone else (by an engineer, or by an editor, if the commit has new messaging). I've heard Google uses this "looks good to me" sign-off process.
