How is this Err handled on use sites? As for the bail below I'd be fine
if it causes some further failure down the road, but if it is a supported
type in pve-firewall above should not cause any actual error or rule
generations to get skipped, besides skipping the nftables-unsupported
ones, obviously.

Also, the linked wiki spots "Last update: Mar/2022" at the top, so a bit
dated. Did you actually try if this is still the case for all of the
listed ones?
