I guess it is users' accounts, so service accounts are exempt? I would hate to see a headless server rebooting and waiting for an age verification from a service account at a power or water sanitation plant...

Maybe all laws should have a "dev environment", starting with the politicians. All their systems will demand their age and proof of age for say 12 months? Toaster, washer, dryer, cell, dishwasher, car, calculators, etc. Then, if they still want to pass the law, 3 months of red teaming by the "general public" for all the systems that have their data. And, if they still want it, go for it.
