Note that there's comparatively little benefit to puberty blockers in F2M cases, because other than the obvious case of breasts, most secondary sex characteristics, even post puberty, can be radically altered by taking male hormones. So you get very little benefit, but the risk side is a lot less clear. For the same reason, most F2M's will be better off delaying both hormonal and surgical transition until well after puberty and perhaps into middle-age, when desistance rates do get very low.

The situation re: M2F is genuinely more challenging, and one has to balance a variety of factors pushing for earlier, not just later intervention.

I don't think this is fair. When we're talking about people this young, concerns about later desistance are very real. Expressing such concerns is in no way equal to preferring that these people "cease to exist".
