Yes, because it means that as Liquid Glass improves with Alan Dye out the door, NNW will automatically benefit from the improvements. Having an app that just follows the current standard native platform conventions is better for users and leads to apps that behave in a predicable way.
Doesn't make sense, the improvements can still be worse than pre-glass, and it's not guaranteed they will be better. Also, what's the rush, why not implement it after it's improved?
The predictability is the opposite - you've changed design, breaking predictable patterns. Also, cutting off users can't be better for users
