Wasn't a voucher shop the plan from the beginning... not sure when that got abandoned.
The way we are currently using them is nothing more than a distraction from DEC, we definitely need to stop using it as a discount token.
Removing vouchers entirely is an appealing option as well (multiple node holder here) unless they can deliver on the "exclusive access" angle which this prop covers with a minimal amount of work, so I will vote for it.
Removing vouchers entirely will always be on the table until it happens, so I think we should lean towards options like this one first.
Also, if they aren't removed entirely, the one spot vouchers should remain as a discount token for is node purchases.
