Tracked as a feature on MAAS backlog (internal ref. PF-3204)

Given that this is fixed in netplan.io is the netplan project task still valid?

No, it was implemented & released upstream as of https://github.com/canonical/netplan/pull/283 so the netplan project task can be closed.

FYI: The work will still be backported to Jammy via LP: #1988447
