Barely but importantly. With bitcoin for every user it is still feasible even on raspberry pi to download and verify the whole chain for themselves. Not so for ethereum even with high end computers. I guess that is their way to phase in PoS scam, but it has nothing to do with “preserving the security model”. Utxo commitment is definitely a shortcut that bitcoin will eventually implement, but it can only work reliably for long timeframes especially when you have “disturbances in the force” like what happened with BCH last year. “Known” blockhash from several months back is something that can easily be faked unless you actually fetch all the history and verify.
