       | It's worth it, dude. That there are people working on the kernel
       | who aren't terrified of the current situation is genuinely
       | worrying.

         | Why is this worth it? I'm not saying it isn't, but it's
         | reasonable for people to want very clear wins, and no
         | alternative, for this kind of massive change which adds a
         | little more cognitive load to everyone, forever.

       | something being legal or illegal. If a thing is facilitating you
