It seems like they only add more debug info, and don't remove anything - so we'd expect an increase in the size, certainly not a decrease. That means, to me, there's probably a mistake in the measurement somehow?

that still seems very surprising - this change is specifically intended to add more debug info, is it not? So do you have any ideas/theories as to why that's not showing up in the data?
