a large part of the reason is that the prostate is hard to remove, so they just don't try to do it

We live in an age when loads of people get heart and kidney transplants, double lung transplants and have all sorts of brain surgeries. When babies with heart defects are having major heart surgery to correct defects whilst still in their mother's wombs. When surgeons are doing extensive surgeries lasting many hours on males to make fauxginas out of a "crazy quilt" of tissues taken from the scrotum, penis, bowel and/or the peritoneum - the lining of the abdomen - and on females to make fake penises by carving all the flesh and nerves off the forearm and relocating and refashioning them in the groin. When women's internal organs are routinely removed or fucked with as in all the cases of surgical mesh.

In today's male facial feminization surgeries, the procedures surgeons often use are extreme and IMO grotesque. Sometimes entire parts of the front skull are removed so they can be sawn down when not attached to the patient:

people (men) with a larger brow protrusion require a more involved procedure. In these cases, the front of the brow bone is entirely removed, temporarily exposing the sinus cavity behind it. The removed bone is then contoured separately and replaced, so it lies flat.

But removing the prostate is too hard for current-day surgeons to do? Ha ha ha.

According to Johns Hopkins, not exactly a slouch in the field of medicine, a

A prostatectomy takes about two hours. You will be under general anesthesia, so you’ll be completely asleep. During the surgery, your doctor will:

1. Make a small incision to gain access to your prostate.
2. Remove the prostate.
3. Reconnect the bladder to the urethra, the tube that carries urine outside of the body.
4. Connect a catheter to the bladder, which allows urine to drain while the area heals.

You should expect to be in the hospital for one night

After you’re sent home, you might find that regular ibuprofen or acetaminophen will be sufficient pain management for the first few days. If over-the-counter medications aren’t enough, your doctor can help you with alternatives.

The idea that prostate removal isn't done coz it's too hard is IMHO total horseshit. I'd wager good money that the major reason it isn't included as a "gender confirming surgery" on TIMs is coz removing the prostate often leads to temporary impotence and longterm erectile dysfunction as well as an inability to produce seminal fluid (issues for all men, including the vast majority -95% - of TIMs who keep their dicks and balls nowadays) and coz the prostate is a major source of sexual pleasure for males whether or not they have their dicks and balls. All the surgeons who've pioneered the various "sex change" and "gender confirmation" surgeries happen to be men. And men aren't interested in doing anything that might cause their fellow men to lose an organ that is key to producing seminal fluid and providing males with sexual pleasure.
