Again, mtf or any transgender issue can be solved with birth certificates. It doesn’t require genetic testing. Genetic testing is targeted at humans that according to all our traditional laws and practices are treated as female, yet may potentially be banned from female sports.

What are you talking about? This is not about transgender at all. For those you could require a birth certificate. This is targeting women that are born as girls but, due to genetic anomalies, do not appear as such on genetic tests. Many (most?) would never discover the genetic anomaly during their lifetime.
