I think most people that are so eagerly waiting for ART already have their systems set up pretty tight and are greatly enjoying them with their current bass management. I know I do

.
The whole hype around ART started way to early and by now people are expecting so much that a lot of critical listeners with good Audy/REW/MSO setups might be disappointed at the end. My experience with ART was with the dealer setup and given all the hi-end gear involved (Perlisten speakers etc.), it was still making me wonder if that bass is actually the bass I would want. Extremely tight but not nearly as powerful as I am used to. I could use some lower decay below 45hz, true, but not sure I want to give up a big slice of SPL for that. Have no idea how they have set-up their Storm 16 ART system so the experience is pretty much irrelevant - they were clear that they would not want me to mess with their calibration, nor I would know how to do it without spending 100 hours in their shop.
Definitively agree that roadmap would be helpful, but then if they can't stand behind it, better to keep it loose. I do think that D&M will try to pull their muscle and get this done in 2024, but at the end it all depends on Dirac.
In the meantime, instead of obsessing over ART, I am trying to enjoy the worthy contend in my great HT that is occasionally available in the streaming world. Finally watching Masters of Air and yeah, could do that all day long as CA says

Unfortunately have to split it episode by episode by day (if lucky).
