Re: "Windows, and many apps, still suffer from memory leaks."
From your description, it seems the best use for Optane would be as the storage area for page files and temp files namely the Unix swap drive that Windows didn't support for reasons reasonable back in 1990, and sort of supports with ReadyBoost and ReadyDrive.
I suspect a potential use case would be in cloud servers where you are wanting to maximize CPU utilisation and thus would want to keep loads close to the CPU. But then we now have PCIe 5.0 NVMe's...
Also suspect given how recent generations of Intel processors are suspectable to side channel attacks then Optane - developed concurrently with these processor, is also wide open to such attacks.
