@ykakarap Just fyi. Looks like the upgrade test tells us that removing the taint doesn't work at the moment

Mar 2 17:08:50.287: INFO: Unschedulable nodes= 2, maximum value for starting tests= 0

Q: Would it make sense to bring up the topic of in-place propagation on the Machine Pool machines via an issue?
(I guess it depends on MachinePool Machines being implemented first)

But fine for me to add the unitialized taint to MachinePool nodes as well.
