It accelerated for me when I started estrogen, but E improved my life so significantly I obviously would choose that every time.
For me it was more about feeling my penis was out of place, but having a vagina felt too theoretical and I didn't allow myself a direct desire (maybe that was repression).
and zero-depth / vulvoplasties are even safer, cheaper, etc. - and you can get a full depth later if that really becomes necessary (though I personally recommend just getting full-depth vaginoplasty upfront if you think penetration is important to you, my point is just that a zero-depth doesn't rule out a full-depth later).
