This really is a critical feature for adoption in the business space. Multiple sites require addition fields, as has been mentioned a number of times. Plus some sites mis-judge which field is which on those login pages, so the username ends up in an ID box. I'd prefer Proton for our work team, but currently, BitWarden makes more sense just on that basis - even though many other features are preferable in Proton. Even KeepassXC lets you map the custom fields for autofill.
