Whilst I agree with pretty much all that you've said, at the same time the show doesn't afford itself much exposure to many new writers who may take everyone by surprise. That's not in and of itself a bad thing (it affords the show a reliable success rate and a consistency), but if we look at Series 9 - Sarah Dollard is the one and only person who has not written for the 'Who universe' before. With Catherine Tregenna she's one of only two people who have not written for Doctor Who before. And with Whithouse, she's one of only three writers who hadn't written for the show just a year earlier (with Moffat, Gatiss, Mathieson and Harness all having contributed to Series 8).
With a set number of episodes a year, the number of writers per series is quite small as it is - Moffat has alternated between a writing team of seven and eight writers each year so far. Of those, there's never been more than three in any one year who are new. Again, that's not a bad thing and I'm not complaining about it at all (a wholly or even largely new writing team each year sounds like a disaster waiting to happen) but it means that with the majority of contributors to the writing team, the BBC and Moffat will know what to expect on some level. As an example Mark Gatiss, like him or not, has had a mixed reception amongst fans of the show for years - and his efforts in Series 8 and Series 9 are regularly cited as the weakest of the lot despite him being the most frequent contributor to the show after the showrunner himself.
I don't think the BBC needs to change anything about how writers are brought to the show (though if Gatiss writes another poorly received episode and continues to contribute beyond that I'd say it was fair for questions to be raised) but if they are indeed hoping for another Moffat success story then I'd argue that they're going about it all wrong. Even Moffat himself has proved that writing ability and showrunner ability don't
always equate, and it could very well stand to reason that a writer who hasn't delivered a solid classic story could very well be someone who runs the show in a superb direction. I guess it's all about how many risks you're willing to take - I'd wager that the BBC is over-protective of the show to some extent, and that trickles down to an over-protection of Moffat which may have now resulted in the show suffering a quantitative loss as a result of obligations to also deliver Sherlock.
