Should we unwind the pledge to "lose the device" on device drop?

[bradwerth]

I've become convinced that the motivating case for the drop-must-lose-device is not strong enough to overcome the severe weirdness this could introduce. Behold!

let resurrectingPromise;
{
  const device = await adapter.requestDevice();
  resurrectingPromise = device.lost.then(() => {device.someNewProp = 0;});
}
await resurrectingPromise;

In such a case, either the device is never dropped and therefore the code hangs (confusing for the developer), or the device is dropped and the promise brings it temporarily back to life (crazy hard for the embedder to implement correctly). I don't think this is going anywhere good and the initial claim that we need this behavior just to support memory management for C-based user agents is not a strong enough motivator. I'm strongly tempted to unwind the changes made in #4862 and abandon the cleanup in #5032. Any objections?
