That could absolutely be the case, we will see in seven days.
A problem I see with temperature checks is that you can never be sure that the outcome will represent the outcome of the final, official vote. There’s a chance that there’s always some sort of selection bias among those who choose to vote on the temperature check. If you care a lot about the proposal and/or if you’d like to add a new option, you’ll probably make the effort to pay attention to the proposal and vote in the temperature check. If the proposal isn’t important to you, chances are you won’t spend more time on it than needed and just vote in the final vote – not in the temperature check. Based on these assumptions, temperature check votes are not meaningful.
@v3naru recently shared a related comment with some good points in this thread, I’d recommend that we continue the discussion about temperature checks there.
