Yes ok. And legacy code might be a good example where grep works well, if it's fair to argue a greater propensity for things like preprocessors, older languages and custom builds that may not play as well with semantic-level tools, let alone be written with modern tooling in mind.
Lol, I'm not working with COBOL or Fortran. Legacy code in my world means the original developers have left, not that it dates from the 1970s. Mostly I work with PHP, shell scripts, various flavors of SQL, Python, sometimes Rails or other stuff. All things modern LSPs can handle.
