Yes, it's a bad thing to do, it's pretty obvious that it'll scare the bejesus out of some people and even worse, have some chilling effect.
On the other hand the pendulum on ethical boards has gone waaaay in the other direction to the point where a lot of very useful research doesn't get done. The most vivid example being that we don't have human challenge trials with Covid, even now when it's crystal clear that actual risks to young healthy people are close to zero.

So, what's my opinion? Well, an "opinion" would require me to chose one of those two perfectly valid points of view. But if I had to, I'd say the travesty that is "ethics boards" has become a bureaucracy so rotten it doesn't even perform its original function of stopping vaguely unethical research, and has instead gone completely the way of paper pushing. While, of course, still drawing a salary from making sure tens of thousands of people are dying needlessly.
