I don't think there was ever a structural issue between the hole sizes. I used to drill out all my rims pre-tubless and never had one fail at the valve hole though I killed more than a few. It's more a throwback to the perception that high-end bikes have Presta and cheap bikes have Schrader?
I wouldn't have guessed the apples:apples weight comparison was different but I'm not much of a weight weenie and I'm sure if it's more than a gram you're on to something.
Can't stand those screw-on adapters! I do change the valve cores often in my Presta tubeless setups which I think solves half the reason folks dislike them but certainly drilling rims out for Schrader would be my winning strategy.
