I'm also not 100% convinced anymore we need more than just session history at this point. This needs much more thinking and a couple more prerequisite tasks before we can embark in this journey, which could get hairy. Like the Settings one, Mathieu, so at this point that one takes priority over this one. After you finish the session history of course.

I'm lacking the time to scour for the e-mails that consolidated the need for running multiple sessions concurrently, I faintly remember some arguments from Aleksey, so maybe he can get back to us on this matter.
