[Too]

While the use case for recipes stying alive is very useful. Should this responsibility really be delegated to each website?

I didn’t even know this was a feature of my browser. Say for example I write a shopping list based on the recipe web page, then go to the supermarket to buy the ingredients, leaving the tab open because I will need the instructions tomorrow for the cooking. Now my computer will be forced on during the rest of day based on the choice of the website owner?! Wtf. What if I leave the tablet open after finishing cooking, Is there any timeout on this thing or will that differ depending on each website?

Honestly this feature is really badly thought through. It should be a feature of the OS and not up to random web sites without even asking for permission.

Putting my most cynical hat on you could imagine advertisers enabling this on every website so you are more likely to be exposed to their ads.
