Five years is not nearly long enough, it's a start, a good start (especially with such high success rate), but not nearly enough time to base anything on (Especially MEDICAL PRACTICE, OR LEGISLATION), and it would be just repeating the tragedy of "As Nature Made Him: The Boy who was Raised as a Girl" to use this study as anything else, other than that: "a beginning of a study".
Until another 20 years have passed, when the results of this study can be used in a more productive manner.

The "As Nature Made Him: The Boy who was Raised as a Girl study" put us back years if not decades in medical practices, and understanding of the biology of gender, because the notion of "success" was rushed.
It took over nine years to begin seeing the actual outcome (https://embryo.asu.edu/pages/david-reimer-and-john -money-gender-reassignment-controversy-johnjoan-case), and decades after that to see the true outcome, which unfortunately was not a happy outcome.
