What is the benefit of moving these rules inside &:not(.is-not-stacked-on-mobile) > .wp-block-column?
These previously were on .wp-block-column directly, and it was a lot cleaner. I haven't checked, but would it not be simpler to have these in .wp-block-column like before, and then simply override these rules where necessary in &.is-not-stacked-on-mobile?
Is there a reason I'm missing for the added complexity?

The main benefit is that using the :not() rules avoids duplicate code. There are also some !important rules here, so we'd need to override those with more !important rules. 😅

Yes, it's an awkward rule, but results in fewer lines of CSS, while preserving the existing styling / similar specificity. I couldn't quite come up with a neat way to handle it otherwise, so it was a bit of a trade-off! 😅

// Only add two column styling if there are two or more columns

// assigns its own width as an inline style, which should take effect
