I'd rather avoid the message for a bit longer too, while not a warning
anymore it can still rather scare users reading this when opening any
start task log of such a machine and then maybe even wonder why they
do not get warned about it. If they are fine to use for longer in PVE,
like we discussed of list before the holidays (I might have forgotten
some details though), then there probably should be no deprecation
warning at all until the next release when they are indeed deprecated
for our POV, then this might even stay a warning.
