Apple Seeds Fourth Beta of tvOS 15.2 to Developers

tvOS hasn't added any major feature to a minor release since the very first tvOS. 9.2 released 5 months later added substantial changes and new features.

As for the feedback, Apple might as well call it a blackhole.

tvOS updates are often minor in scale, focusing on under-the-hood bug fixes and improvements rather than major outward-facing changes. There's no word yet on what's included in tvOS 15.2 update, but we'll update this article should anything new be found.

I think a couple here would badly like to see a new version of tvOS Apple TV app like they did recently for IPadOS 15.2 beta. The only question is how many submit feedback reports to Apple about that app. ;)

I said "tvOS hasn't added any major feature to a minor release" -- aside from Apple Music lossless audio and support for new Apple TV 4K hardware with calibration feature, none of the features you mentioned were introduced on minor versions.

And yes, I am aware that tvOS occasionally adds new service-oriented features on minor versions, such as improved Apple TV+ support, Apple Fitness+, and aforementioned improvements to Apple Music app. But by and large, Apple will reserve new features for major releases.
