No, absolutely not vice versa: gender dysphoria is well-documented and reasonably reliable ways (even given its rarity) exist to detect it. So it's a mistake to say that it's a problem to compromise the care of the second group out of worries that the first group exists. We know the first group exists, and we have a pretty good idea of how to find them.

I think it's worth paying a good deal of attention to determine to what extent the second group exists (i.e. outside of some higher-profile cases, how often does this happen, and if there is regret is it because of a contagion-like phenomenon or merely that people aren't as heavily ostracized as they used to be so they feel more liberated to speak what they're feeling, even if what they're feeling ends up being confused).
