Cishet-ally with a genuine concern;
I understand the secondary characteristics being an issue when you are genuinely suffering with dysmorphia. However, to the original commenter's point, there are absolutely reports of people on all sides of transition who wish they hadn't messed so much with formative biology.
This is not to suggest I don't accept that some people know from birth they are inhabiting the wrong body, but there are some basic human physiological developments that puberty enables besides secondary sex characteristics. Messing with that has left a decent number of people with a body that now feels wrong on multiple levels. The characteristics one was biologically predisposed to are stunted, but the desired ones are also now incongruous because the body wasn't given a chance to properly develop. I will admit I have seen far fewer of these cases than I have of people successfully and happily transitioning, but having a child's voice in a rather androgynous and sad not-quite-adult body isn't something I think most people would actually pine for regardless of current dysmorphia.
I don't have any skin in the game myself, but I also don't want people to suffer. HRT does need to be more readily accessible than it currently is in most of the world, but I also don't think it should be in vending machines for the reasons I and the top commenter made.
