Thanks for the explanation Giuliano.

The OpenZFS project now works around the issue by forcing version 1.8 or ne=
wer:
https://github.com/openzfs/zfs/commit/a9655fc2bd1f

And the project's *.abi files have been regenerated with v1.8:
https://github.com/openzfs/zfs/commit/6ea058da16cc

Hopefully in the future there won't be any silent changes in the XML file
format which trigger abidiff.

Closing this. Thanks again.
