I wrote a kind of guide on how to do it here. It may or may not work with current versions. It’s based on building up from scratch, so your mileage may vary.
The instructions should all just be there somewhere in the GitHub link. Otherwise it’s just repository cloning. As for the deprecated libraries, they were mainly the python okes, since that’s what the launcher used.
That’s cool @qqMajiKpp
I’m talking building up from the ground up here, so breaking things isn’t a big deal. If you don’t want to, you don’t have have to. I’m not sure what a power user exactly is, but I guess if you don’t want bleeding edge, you also don’t need to do that to. It’s entirely up to you.
Some people just need to have “bleeding edge”/SED/SID features to have certain functions such as graphic drivers etc to work. That’s how we got things working with Lima. Also, recently, I had to use a SED modification on a kernel compilation to fix the dreaded screen flicked problem lots of people have reported.
