Will likely reduce the budgets even more after the fixes or perhaps assign per-bundle specific ones too. Wondering if the dev demos can be setup in a way that can also do the budget bundling checks, but I suppose this will do for a safety net for now.

Intentionally merging with bundle budgets failing test to be resolved by the related fixes.
