I haven't read through all the replies in the thread (It's long!). But, throwing out my pair of pennies.
My understanding of how things work, is that someone, presenting totally as a man, could walk into a surgeons office, and get FFS, BA, and VFS, without having gone through any form of gatekeeping whatsoever. No shrinks. No RLE. Nothing. All it requires is money.
Now, it seems to me, that those things, being publically presentable, are waaaaay more likely to cause psychological issues and/or regret for someone who is "not really sure about changing gender."
It also seems to me, that most guys wont get their penis lopped off on a whim. Sure, perhaps there are a handful of people that regret GRS. But, given ANY choice there will ALWAYS be a handful of people who regret making the choice they made. And given that, again, most guys want nothing more than to keep their penis above all else, I can't see getting rid of the RLE increasing the number of people who regret GRS.
And also, because what's in my pants is private, and only I chose who gets to see it, if I should regret GRS then only I have to deal with it. Whereas all the other surgeries, being very prominently public, effect not only me but everyone else around me should I regret it. So, I don't get it. Why is getting a boob job and having my voice surgically feminized without RLE perfectly okay, but I have to wait a very dysphoric year to get a vagina?
Granted in my case it's a pointless argument. For me finances dictate when I can get it done, not the SoC - it'll be waaaaaay longer than a year for me to save up that kind of money. Unless I can rob a bank and somehow evade getting caught until after surgery
