This has been a thing since Linux kernel version 5.0.

How come it doesn't work? Which compositor are you using?

I'm currently using Gentoo. That means I should also grow my own food...

To complement your answer, usually people want tree-sitter not only for smart selections, but because of syntax highlighting.

Kakoune has the best of both worlds: https://github.com/kak-lsp/kak-lsp supports semantic highlights from LSP servers, but we also have projects like https://github.com/phaazon/kak-tree-sitter in case you want highlighting from tree-sitter.

Well, that's Fedora, my friend. On Gentoo it's still the same.

Short answer: if you're asking this, then it's not worth it.

Long answer: Ditching systemd in favor of something else is usually an act of experimentation. Folks that do it usually have had a negative experience with systemd, be it in its usage or from a problem they had that prevented them to boot their computers due to the tightly-coupled relationship between mainstream distros and systemd.

Also, preference is involved here, so you might prefer to assemble your system with independent pieces instead of a full-blown suite like systemd's. You might also not like systemd's UX so, as a user, you end up wanting to try something else.

Ok but nowadays there are alternatives to systemd (OpenRC, runit). Not necessarily better, just alternatives. No SysV init involved.

I'm not. But I installed Gentoo on a x86 tablet, it was fun.

I like compiling Gentoo on tablets

I also want to avoid being too dependent on Google's service and then get locked behind a paywall or something. One never knows.

Do you create slides with it? Which input format do you use for that? I usually use LaTeX for slides but would be interested in an alternative.
