None of the upgrades in ES6/ES7 obviate the need for frameworks. Maybe some libraries are made redundant, but frameworks address more interesting abstractions that a general language probably shouldn't cover anyway. Frameworks seem to adopt more opinions about implementation, and help unite a team over a set of ideas, and enable them to move faster and reason about similar problems in similar ways. Hopefully that team has picked a framework that is also well-suited towards the problem they're solving.
