The problem with this would be the difference between different scientific fields, and a difference of opinion about what is important to research. For example, blinding will be hard/impossible in some fields due to the nature of the interventions used. And how the control group should be treated (or not) would depend on the goal of the study. I don't think dismissing "stepped wedge" as a bad design is useful for us, but explaining why it's not a good design for ME/CFS (the fluctuating symptoms like @Invisible Woman brought up) might work.
I agree, in this case, unless ive missed something, I think the problem is that the nature of the intervention is to hype patients up to believe they are healthy. Obviously this will then affect their subjective outcomes, especially early on, making it important to have a long follow up where u can also exclude placebo somewhat. And also to check via objective measures how the subjective and objective endpoints correlate. I dont mind stepped wedge in some scenarios either, but here it just seems to me to make the study far worse
