No matter what is planned right now, if this isn’t a PR disaster but the opposite and all the direct filers are gleeful about it, I think it’ll be good enough publicity for them to broaden it to most any use case.
CPAs with a million times more insight may need to correct me there though.
I'd be down with a system that literally just says, "This is what we have on record for you, would you like to file this or dispute it?" Considering they get copies of all your tax documents.
