I think that AI and upscaling technology has improved so much since the Next Gen remaster they can probably do the same with DS9 and a much lower price. And I say this as someone who knows almost nothing about AI or upscaling!
Mmmm... for special effects, the results of a server farm's algorithms are not as noticeable (Babylon 5 is quite good and truly retains its original release feel, while melding live action film that blow the videotape edit out of the water with true sharpness and color detail), but for live action the Artificial treatment still can't hold a candle beyond selective edge enhancement. The 35mms, which continue to slowly rot and - if not manufactured to ideal spec might succomb to vinegar rot sooner than expected, etc - hold exponentially more detail in terms of sharpness and color depth than a SD videotape transfer could ever begin to hold. Compare AI to the remastered film clips on the special blu-ray release. Native still blows AI out of the water and for all the same reasons. It's no contest. Even taking a scan and reducing resolution to SD size and the result still has comparatively more detail.
Even home AI systems like Topaz AI also require a fair bit of tweaking and testing, and not all scenes in each episode get augmented perfectly the same way and sometimes whole episodes need total redos. You'd probably spend more kWh cost in electricity bills in umpteen redos in playing with that than going to a legitimate high-quality source that still exists. The films exist, any remastering will pay for itself via blu-ray and streaming after a few years, and the audience is still there.
And, yep, as with TNG, people will bicker about DS9 allegedly being a double-dip that's somehow overpriced, with no clue as to the effort in the 35mm restoration, extras made, and how the MSRP for the blu-rays were lower than the original DVDs. People got a steal for TNG on that first day of release, never mind when prices dropped a few years after that.
