I think it helps with tooling, linters, refactoring tools, code generation, etc., if you have a "standard" lexer and parser. The reason being these tools can rely on reasonably standard parsing libraries to take a spec in a common format and then translate input to an AST to take actions on. If you haven't heard the term context-free, you haven't done much parsing; it's ubiquitous there.
