was such discussion possibly a driving force behind the creation of the language server protocol LSP?

which created an interface between meta knowledge about code on one side and user interaction (ide) on the other?

LSP was a pretty inevitable development in software IMO- there are increasingly many codebases where local compilation is a nightmare and you need some kind of remote/distributed build system to manage it for you, and once you have that you need to push xref and indexing out of the IDE as well.
