I think the risk is that it becomes framed as extortion, and would cause some proportion of voters - who at least right after the OSA was put in place remained relatively in favour of elements of it (though the polls have been wildly flawed) - to double down.

Hence, I think a total block would be better than a partial block, because that can be framed as legitimately risk mitigation and would be a lot harder to attack.

That said, some pressure would be better than no pressure, so if the alternative is no block, I'd prefer a partial block.
