just for the record: this got superseded by a v2:
https://lists.proxmox.com/pipermail/pve-devel/2023-August/058691.html
and then later the v4 got applied:
https://lists.proxmox.com/pipermail/pve-devel/2023-August/058742.html
It's helpful to reply to a patch that it is obsolete (just something
short is more than enough), as the existence of a next patch revision
might have been overlooked by reviewers otherwise, letting them
potentially waste more time than required.
