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.
