This is pretty key. If they had added this field 8 years ago, absent any context of swarms of lawmakers salivating for personal info so they can find more children to fuck, or data to sell to their donors, then I wouldn't have thought much of it. The timing is absolutely a critical element of the discussion. Heck, wait until CA has repealed its law, and admitted in embarrassment it was a terrible implementation of child protection, and maybe I'd even be okay with adding the field.

Putting it in now is very much like the nazi standing at your door, holding a hand close to your knob, insisting "I'm not actually searching your house and breaking your 4th amendment rights! I'm just standing here, for no particular reason!"
