Other than the chips that are significantly damaged prior to the updated microcode, why should this be treated differently from the meltdown saga? Fixes for that required significant slowdowns, except in niche applications with trustworthy code or air-gapped systems such that the vulnerability could be ignored. No Recall. Class actions ongoing, but everyone's mostly forgotten about them. More conservative voltages will only lead to small (low single-digit) performance decreases, right? Isn't that less significant a performance hit than meltdown countermeasures? The only way I can imagine performance really tanking would be if Intel has to severely down-rate supported memory speeds as well, if the ring bus can't handle higher memory speeds at slightly reduced voltages.
