I'm not sure about the specifics, but providing something a lot more "batteries-included" seems to be the idea behind Emacs distributions like Spacemacs and Doom Emacs.
One difficulty is that language-specific tools (language servers, linters... etc) are standalone pieces of software with their own dependencies, requirements... etc. It's hard to bundle together a fully "batteries-included" Emacs without figuring out a way to manage native software and services.
I think this is one place where Nix can be a real advantage: even if you don't care about Nix's reproducibility, it's ability to manage Emacs, Emacs packages and language-specific tools is pretty unparalleled. If I had some more time on my hands, I would try putting together a Nix-based Emacs "distribution" with some easy way to configure which languages you want to work with. Coupled with lsp-mode and language-servers, this has some real potential!
