Correct, they should be used for code (and code-like artifacts).
If that's the only change, and it's wrongly appliedincorrect usage, reject as "no improvement whatsoever" or "causes harm".
I don't have a problem with filenames, paths, API methods, commands, etc.–those are computery "artifacts" that should be differentiated from expository text. Products, trademarks, etc. aren't.
When emphasis or clarification is needed for non-artifacts we have italics and bold.
