Terminology is changing a lot in the younger generation of trans people - in my sphere, GRS does in fact mean genital reconstruction surgery.
From my understanding we're actually trying to get away from sex-based terminology as well, and encouraging that the physical characteristics of what most people know as "sex" also be seen as a social construct.
So basically, a trans women still has a female body, because it is her body and she is female. Her actual anatomy wouldn't have a bearing on whether she's female "bodied," only her gender. Especially because many people exist who can't fall into the binary spectrum of "male versus female bodied"
These people aren't sexless or genderless or anything else, their body is whatever their gender is. I hope that makes sense.
I don't even like to use the terms "MTF" or "FTM" anymore, since they insinuate that the person used to be a different gender and is now "becoming" something else. Just my perspective.
