This is just recognizing the status quo. Pretty much no desktop or mobile or web software is handling "unlikely to fail" allocations. And how exactly do you expect them to handle it? If, say, it's a desktop app that's rendering a widget, and as part of that it needs to allocate a string, and that fails - how does it recover?

Panic on OOM is perfectly reasonable for most.

And yes, panics shouldn't be catchable. That's the whole point.
