No adaptive profile or non destructive AI denoise in Lightroom?

The features mentioned are Beta or Technology Preview. Which means Adobe wants to get more of the fundamentals right before adapting it to the other raw processors like Lightroom.

An Adobe employee has already stated here in Adobe Community that non-destructive Enhance is coming to Lightroom. Just not right now.

ACR is basically lightroom inside of photoshop and features being dropped there first is super disrespectful.

Actually, it’s the other way around. Camera Raw is the reference module, partly because it was developed first, and partly because in its plug-in form it’s called on by multiple applications such as Photoshop, Bridge, and After Effects. Lightroom and Lightroom Classic use an embedded form of the Camera Raw code. That’s probably a big reason for why things are. The base code has to be right before hooking it up to multiple other apps.

When they bring it Lightroom/Lightroom Classic, it can’t be used as is from ACR. They also have to work out how the non-destructive Enhance data will be stored in the cloud server database or local catalog. ACR uses local sidecar files.

Many previous features were rolled out simultaneously in these apps. Maybe that was their intention, but maybe they ran into complications on the Lightroom side and decided to let it loose in ACR for public testing instead of holding it back from everyone. Other features are released unevenly in various directions; for example, Quick Actions were added to the Lightroom mobile and web app versions but not (yet) in the macOS or Windows versions of Lightroom, and are not yet in ACR either.

The explanation for why things don’t always happen the same way is likely to be some form of “it depends.”

I spend the most time in Lightroom Classic, but it doesn’t bother me that I can’t use the non-destructive Enhance features yet. I am reading about how people turning on the non-destructive Enhance setting in Technology Preview in ACR are running into bugs, as expected since it’s not done. Some here are also reporting that ACR seems to run slower with that code enabled.

I know I don’t speak for everyone, but I don’t mind waiting until it’s more polished so that I can use it without hassles.

@SplatterPop , you stated. "ACR is basically lightroom inside of photoshop and features being dropped there first is super disrespectful."

Adobe Camera Raw has been in existence prior to the development and release of Lightroom in Feb 2007. 
Camera Raw is a Plug-in which runs with PS.

Lightroom is an independent application and has the Camera Raw processing engin built into the Lightroom application.

The Camera Raw team develops improvements to the raw processing engine and new features. These are then passed to the Lightroom team for implementation in the Lightroom application, that's why you may see new features in Camera Raw shortly before LrC.
