I firmly believe that if your site generates > 500ms main thread tasks for a sizeable fraction of users (say, 10%?), then browsers should put a "slow" icon in the URL bar and send a bloom filter down that opts your site into "single thread mode" for all users.
In this mode the browser would:
- disable off-thread compile and GC
- block scrolling on main-thread tasks
- animate on the main thread
- block on image decode
That we don't do this today is a failure of imagination.
