You bring up good points. 1. Higher mass will slow you down climbing, but the question is how much. Realistically, the differences are very small. We tested a 650B randonneur bike with 42 mm tires against a titanium road bike with 25s. Both were excellent bikes, and their speed was the same. Clearly, the difference in weight got lost among other, more important factors.
2. Yes, sidewall deformation is an issue - that is the start of the sidewall collapse under high cornering loads. That is why you need to run slightly higher pressures with supple tires. Even at those higher pressures, the supple tires are much faster and more comfortable.
