Yes, I think there is a lot of this happening.
I saw a number of faces post FFS that I would still say should have done more or that look not "100% passable" or more often that look "jumbled" - like the forehead is feminine but the chin is masculine, almost like a mixed puzzle of two people. But people will tell them they look good because they want to hear it or say that they are so happy and no one wants to bust in with "well, if its good enough for you to be happy, fine, but I would not be happy with it, so maybe I should choose a different surgeon".
Sometimes I even see such pictures presented in galleries or on online posts or ads made by the surgeons or associates which puzzles me because I am not sure if the surgeons really like those outcomes or if they feel compelled to put them online if a patient gives an ok. I think often the patient or sometimes also the surgeons and probably other patients said that something is not needed and then its missing, but occasionally those parts have actually been worked on and still are not so good.
But its really hard to say so publicly because the general consent is to be uplifting, that trans people already suffer so much abuse that at least we should be saying always nice things. In addition to that, if surgeons or their associates read in a forum or group, it is a lot harder to comment negatively on them - I saw occasionally posts retracted because of this - former patients do not want to be publicly critical about the surgeons, patients who have a surgeon on their short list also do not want to ask too much ... its really complicated
I think how much surgeons recommend varies a lot. I have gotten quotes for only two minor procedures and I have gotten some for about 10 procedures to be done in 2 separate surgeries... This make sit increadibly hard to really choose what is needed. If a lot of people tell you that you do not need a procedure or that you do not need FFS at all but some will tell you to do everything possible - who do you believe?
