PVF: Take back a stolen right

After a recent [worker
revolt](paritytech/polkadot#7538), they managed to gain
a small amount of freedom from the landowner host. But after the failed
[proletariat revolution](paritytech/polkadot#7570),
there were mass migrations and we ended up in a new repo. The capitalists took
advantage of the confusion to secretly take away a workers' right. We must undo
this before it goes too far.
