This is fair, I have been looking at the Haltech 2500 Elite and it has absolutely every feature I want (and a TON of engine safeties I'd LOVE to have) but the main issue I'm seeing is just a plain lack of information in the community. There seems to be almost no threads between here or NASIOC that has anyone breaking down what they had to do in order to run one, if they were able to maintain all of the OEM functionality, ect. I have noticed that there are some pretty good looking PnP harnesses but it doesn't really specify to what degree everything works.

I plan on getting the brewedmotorsports plug n play kit for my 2020.
They told me everything works just like stock. You can use the SI drive dial to switch map as with an AP, and DCCD works, according to what they told me. Not sure what else there is to worry about not working honestly.
I was looking at boomslang as well but they have almost no information whatsoever and it kinda puts me off. It's also likely that brewed is using their harness or atleast a version of it, anyway.

I don't see it listed on their website, I do like the haltech mounting bracket though. I haven't picked up the brewed harness yet but that's still my plan unless I see more info on the kosmic one.
