What is this change in biology and physiology that thousands/millions of us working in fields where biological sex is of significant relevance haven't been brought up to speed in a formal and rigorous way.
Do you honestly argue that biological sex no longer matters for things like your haemoglobin, glomerular filtration rate, growth charts, weight charts, drug dosing etc? I'm currently in the process of supporting a friend being diagnosed with an inherited disorder where the medical professionals are very interested in some family members and not others...based on....(spoiler, it's not gender identity)....
There are thousands of institutions , services and professionals carrying on basing absolutely every single thing they do on biological sex as per the "old" ways and I'm unaware of the plans to ensure all cpd brings everyone up to speed....
