Browsers should probably warn if a site on which you are filling forms with personal information or payment methods have been issued with KYC or not. And clearly state to whom physical persona or enterprise that certificate was issued.
Though I worry about the barrier from many people to get those certificates and then privacy concerns. It’s a balance between privacy and democracy and fighting scams. My guess is that browsers should only warn in certain websites, but in which websites and how to detect them… That eludes me, seems complex.
