Although for volatile volumes in particular it might be possible to get away with (optionally, configured per-volume) attempting to set the nocow flag and ignoring any failures. Not sure if even that is worth implementing though, when it's already possible to configure a dedicated nocow pool for those volumes. The filesystem specificity I was thinking of is a bigger issue with other (snap_on_start or save_on_stop) volume types. E.g. on Btrfs you can only do a reflink ioctl if the source and destination files have the same nocow status - a notion that is perfectly captured by making the whole pool directory nocow or not, without any convoluted logic in the file-reflink driver.
