Sure, but that case could be made for everything since the creation of Splinterlands - everything was created once... Vouchers are part of SL for at least 4 years when I started. Based on that - no, it's not revoking a past decision. It's a distraction, leading away from the real problems that are not targeted. If the whole situation wasn't as dire as it is - sure, fix a minor issue that comes up with Vouchers by deleting them. But right now, the proposal just a waste of ressources that should be spent on fixing real issues.
