See this proposal here. We don’t have the ability to force migrate the v2.1 LPs under the Ugradeability Clause.
By mandating a forced migration, token owners are no longer left with the choice to move into the new system or stay in the old one. The elimination of that choice is a material breach of the Ugradeability Clause.
The worst thing you can do is force migrate the v2.1 LPs into B3. Although that is a tempting solution for all vBNT holders, be warned of the legal implications of such actions. It’s direct contradiction to the Ugradeability Clause and would likely be a material breach of contract. Even in the absence of a lawsuit, there would be FUD to no end.
tl;dr - I think option to exit via v2.1 should happen even WITHOUT a vote because the Upgradeability Clause is crystal clear on its face, and these terms were already voted in by the DAO.
