I’m personally of the belief that a remaster should be the best possible version of whatever was originally produced, so I suppose that means I’m not in favour of correcting mistakes like those. It’s not a hill I’d be willing to die on, but I would prefer it to accurately reflect the work that was done at the time.
I'll go further and say I'm not in favor of remasters. I want everything original, low res warts and all. Tasteful enhancements don't really bother me much, but I'm just as happy with the original versions, and consider them a record of history.
If the remaster is to address the quality degradation or to get a better starting point from the original film I am all in favor of it. Just improve the picture/sound quality, not the scenes.
