For some topics there are already signers, who due to their (limited) discretion act as a kind of board on the behalf of NSR holders.
I’m speaking of FLOT and the liquidity operations.
Such a thing as a protocol upgrade can’t be decided by the board, as it’s the minters who need to decide this. They cast votes while minting.
Even if a board decided that the protocol from a date on where to be upgraded, a majority of shares continuing to mint on the old protocol would void that decision.
Still it’s a difference between a simple majority and 90%.
That number was chosen that high to make the network after the switch more reliable.
Such an imporant step like introducing asset voting needs broad consensus.
Better wait a bit longer and raise awareness for the duties of a BKS holder while waiting
