Internationalization is a strong argument.

I don’t like it, but you might be right. I’d still prefer a layer of abstraction between config file keys/comments so your configuration can be localized, but there are additional issues here with user-vs-author comments which the UI solution wouldn’t need to consider.

Of course you are correct, I couldn’t imagine teaching grep to my grandpa, most relatives, or even all coworkers. It shouldn’t be necessary, but it would be lovely if this was always an option. I’d much prefer having control, than an opaque system that migrates my settings forwards. Maybe I’m advocating for a system that supports both?

Thank you for posting, I never considered this, I need to think about it.
