No, you're trying to adjust your view of my opinions to your liking.
The stage striking system is designed to allow players to remove from the initial list the stages that have the greatest negative impact on their characters, typically relative to the given match-ups. Whether by coincidence or not, Battlefield happens to be one of the more common stages that people end up on. I've made note that Smash has the somewhat odd system of allowing stages that are not available for selection at all during the first round of a set, and have been discussing this... elsewhere.
Extending that to striking down to the stages that will be used for the entirety of the set, then, minimizes the impact of stage selection on match-up. There's a possibility of this killing what some see as a crucial element of Smash - potential stage variety - but I've been interested in seeing how it might change the emphasis of the other element of counterpicking - switching characters.
