The middle points on the spectrum that enable partial opt-in are a muddle that don't do much to discourage continuing expansion of bad behaviour. But perhaps we could use it as a forcing function to increase use of islands of isolation (e.g. `contain` + Shadow DOM)?
How would all of that work? First, we need page-level opt-in (as the effects of readback are global, rather than local to the script doing the reading). This would *silently* change the behaviour of expensive style readbacks...
