The announcement of the original games being delisted has even thrust doubt onto the future of S3AIR, which is currently the best way to play 3&K on PC. Currently it requires a Steam copy of 3&K, which is pretty cheap. Once 3&K is off Steam, there's not really any other storefronts offering the game in any accessible manner, so there won't be an accessible way of legally installing S3AIR anymore. The best option being considered right now is to find a way to use Origins instead of the S3K rom, but that does come with a significant price bump that would make AIR much less accessible.
And that's in addition to all the games preservationist arguments you can think of, which is certainly I have a grievance with regarding the delisting. This is going to make it harder to legally play the original games on PC for people who don't yet own it, as well as their romhacks.
This whole thing is certainly turning into a huge mess. I really hope the release itself doesn't embarrass the situation any further. Between the high price, weird DLC packs, original games getting delisted, etc. We really need all the good news we can get.
