Habras Profiles and subdomains ...

I noticed an interesting thing - the members of the Habr team have a profile address like this:
deniskin.habrahabr.ru/profile
whereas in ordinary Habrayuzer like this:
www.habrahabr.ru/people/mozaic

Question: in the bright future, will everyone have profiles of the first type or will everything remain the same?

I think with the introduction of personal blogs on Habré, the first option is preferable.
