> However, the point of all this discussion is that Lisp doesn't provide good enough language servers for modern editors,

They use the "language server" model since a long time, before Microsoft's LSP existed. Thus the need isn't really there, unless one wants to develop with Microsoft products (or similar) and get the needed extensions for Lisp into those Microsoft driven standards. If there were a real need and a real benefit, there would be some better adoption on the Lisp side.
