You'd need a dependency graph of optimizations, to understand where a new dependency would cause other optimizations to need to potentially be disrupted. This doesn't seem like a hardfast cant. We keep getting arguments against doing stuff because it might not be performant. I don't disregard those concerns entirely. But I think we also over-actively forbid, we prematurely optimize by pruning possibility, all too often.
