The deprecation was there for a while indeed and dropped by upstream
for 6.8-rc1. But it looks systemd is adressing this with

https://github.com/systemd/systemd/commit/e3828d7103a99a15a1e947ba3063294ead590631

As we wont apply a local Debian patch unless upstream Linux decides to
facilitate this by adding a noop option back, then I think it's best
to reassign this bug to systemd and close it once the above change is
applied.

Salvatore
