And the UTXO bloat potential is twice as large and the cost of that UTXO bloat is significantly reduced. So you're basically gutting the most of the gain from weight, making something incompatible, etc. I'm not sure what to explain-- even that page on segwit.org explains that the values are selected to balance worst case costs not to optimize one to the total exclusion of others. Raw size is not very relevant in the long run, but if your goal were to optimize for it (which it seems to be), then the limit should be pure size.
