I don’t think that people who don't write or never wrote software should have a place in a software development team. We don’t allow scrum masters and agile coaches in hospitals and ask them to “improve the process”, because we know the only “improvement” we will get is millions of dead and injured. But for whatever reason we allow freshly minted certified scrum masters to lecture seasoned professionals on process, to organise 19 meetings a day to discuss the differences between scrum and agile and, in general, to unleash havoc and destruction.
