What about a distinction between what is necessary to achieve gender transition versus what is necessary because of gender transition? For those who have had vagioplasty, they have basically an ongoing open wound that has to be properly dealt with or else there is a risk of infection and death.

Even those who de-transition, like Walter Heyer, have ongoing health issues.

I was 50 when I had the breast implants removed, but the next few years were spent in confusion and counseling. In 1996, at the age of 55, I was finally free from the desire to live as a woman and changed my legal documents back to Walt, my biologically correct male sex. I still have scars on my chest, reminders of the gender detour that cost me 13 years of my life. I am on a hormone regimen to try to regulate a system that is permanently altered.
The amendment could have been better written IMO. There should be no money for helping someone to transition, but a case by case basis for meeting the actual health needs of people who have already transitioned.
