Thanks for your comment, support and advice! I think that's a really good point that the main challenge here is engagement and adherence, and it's obviously something we're always looking at and trying to improve.

In terms of drifting away from evidence based approaches, that's definitely a risk and a temptation for everyone in this space, and links to some of the other commenters fears here as well. It's a slippery slope we're well aware of and which we don't want to slide down.
