I'm choosing to interpret this as a sign that they are aware of the controversy and are open to considering alternatives. If they're asking for feedback, that means there's a chance they'll act on it.

The part I find strange about all this is that apparently Switch 2 titles just can't use smaller ROM sizes, and that's why certain third parties don't want to pay increased manufacturing costs to put smaller titles on larger cartridges. But... why are they apparently not able to use smaller carts?

We're seeing cross-gen releases where the Switch 1 version is on the cart and the Switch 2 version is not. They've even got dual-mode carts for games that contain the Switch 1 base game and Switch 2 upgrade DLC. These smaller carts exist and the Switch 2 can read them. So I'm puzzled as to why they can't use these same carts for Switch 2 games.
