I mean the medium-term response from someone who wants to make it their full-time work project to solve this problem for everyone. For someone who doesn’t have the political clout to change Chrome directly, a plugin or fork could probably also be made to solve the problem.

Personally what I’d like to see in a browser is a more explicit and configurable policy about how many resources to devote to background tabs.

The remote-execution solution is incredibly bandwidth-heavy, costs money, hands all browsing data over to a third party, creates an unnecessary dependency on a startup company that might fail or get bought at any time, and takes a ton of control out of end-users’ hands.
