I think that is true, but it would have to be a better solution. Some groups heavily push for this reformation of online identity but most of them have in common that they want to strongly bind online identity to your offline one. That simply isn't desirable in many cases.
iirc online identity used to be tied to your public key signature ? Might be too technical for most population to use, but the ideal solution is already there I think ?
