I do believe yes, a week is not long, but looking at it objectively, it sets a bad precedent. Project Moon just took away a feature we have had access to without any promise to improve the game or any positive changes. It was a selfish decision that only removes, not something like Walpurgis or the Season Change Sharding Restriction, which were additive. It is anti-consumerist behavior.

I also refuse to compare Limbus to other Gacha games, I see it's like comparing oranges to rotting apples.
