Agreed. The design certainly will include the adaptability and expansion for a future roof. Bronfman doesn't have enough $ to finance a roof at the moment since it would add another ~$300M to the price tag. The roof would also be unused for 95% of the time since the team would only play here in summer so it's not much of a priority at the moment and cuts costs by a big bunch. This is actually somewhat the reason why we're splitting seasons and not relocating altogether, it comes down to financing the roof. If our investors were able to finance a full stadium witn roof, they'd be asking for full relocation. It wouldn't make sense otherwise, from an investment perspective.
So as a transition, no roof is okay because the weather will allow for play outdoors during the split season and it also allows the investors to bring a team to town. Good compromise.
