In my opinion, the 33 to 51 ratio in the vote clearly indicates the need to introduce the option to switch between game modes with the mutual consent of the players (in the form of a checkbox).
Because after the checkbox is introduced, there will be a vote on whether to make the checkbox mandatory.
Then the same arguments will be repeated in a second round, dividing players into those who like and dislike the checkbox... two-grid tournaments... you remember how it was in SoD vs. Warlords.
Therefore, it is better to address the issue at an early stage.
