Uh, either I'm reading this wrong or you're confused. Troons tend *not* to get bottom surgery and tend to be the ones who push "lady sticks" and claim the penis is just a big clitoris that squirts. I do know there is a faction of troon-types that get vaginoplasty, and are equally as adamant that it is exactly like a vagina in every way -- and for these folks they place all their validation eggs in the bottom surgery basket. But in my experience the former type is more common. (Spoiler, they're hypocrites.)
Non-crazy transsexual people are indeed divided on bottom surgeries, but that's usually for logical, practical reasons: they would love to have functional genitalia appear magically, but since that isn't reality, they have to weigh the cost, complications, fertility loss, and lifetime maintenance against their emotional needs. A lot of people go "eh, this is good enough", especially if they're older.
...but as I said during the orchi saga, I don't get why everyone is so riled up about whether or not Our Heroine gets surgery. It's content either way.
