And the fact is that anyone working professionally was using an IDE, and anyone else was fine with grepping and using ctags. I think LSP is only truly useful in two contexts, global symbols (even with namespacing) and confusing imports. In language like C, you mostly have a few structs and functions, and for the ones in libraries, you only need to include a single header. With Python, the imports are concise and a good references gives you the symbol identifier. But with languages that needs an IDE or LSP, you find yourself dealing with many imports and many identifiers to write a few lines of code and it becomes quickly unmanageable if you don't have completion or autoimports.
