Can I beg you to disregard for a minute the aspects of non-free software
issues that may or may not arise due to someone trying to figure this
out, and focus on the technical side of this?

It's becoming a Russian idiom about "skinning a bear that never been
hunted". I think it was a simple question of: "Has anyone attempted
doing this?" and I expected some conversation about technical
challenges, not a lecture about the dangers of non-free software. It was
my mistake to even mention godforsaken VSCode - I don't even use it, I
don't know why I brought it up. I apologize; Can we please start it over
and forget about GitHub, VSCode, etc.?

>From what I gather, the answer to my original question is: "no, there
wasn't (at least known) attempt to create an LSP server for Elisp"

So let me then ask follow-up questions:

- Has anyone ever tried figuring out something similar? Surely, in 45
  years of Emacs, someone must have done something like that?

- If someone attempts to create a cli tool that potentially could
introspect, lint, format, and maybe even refactor elisp outside of
Emacs, where would they need to be looking?

- Is it possible to build something like this by examining relevant
pieces of C in Emacs codebase?

- Maybe there are parts in REmacs project that would be easier to go
  through?

Thank you!
