Well there have been lot's of articles on for instance lwn.net [1] [2]
[3] describing how to avoid the "overhead" of the page cache when
running on persistent memory.

So if I would be a database developer, I'd look into them and see how
I could exploit this for my needs.

So even if we don't want to call it a promise, it was at least an
advertisement and people are now taking our word for it.
