It's both. As I said before we've spent a lot of time making the file systems less reliant on hardware getting everything right by adding checksums (for metadata everywhere, and non-XFS file systems for data), lsn verifications, etc. And now we go all in to trust a new (in case of nvme very much misdesigned) feature. I'm perfectly fine offering that use, but I'm a lot less excited by automatically using using it due to my deep mistrust of hardware.
