If you read the Home Assistant official announcement, it basically says all the different methods were confusing to new people so they will remove them from end user support documentation and won't take support questions from people using these methods.
However, outside the deprecation of 32bit OSs (which they point out a large portion are on 64bit capable hardware), they are still going to be documenting the other methods in the developer documentation.
I honestly think this is the right move. Their time is being wasted by confusing new users, and supporting 32 bit OSs is literally preventing the development of new functionality. If you want to use a Python environment instead of docker, the developer documentation is there to support advanced users.
