Feature Request: Add Option for generating config file without comments

[knynkwl]

It would be awesome if there was an optional flag --no-comments that would generate the config file without the comments.

Thanks!

Agree this would be useful, we could probably do it by pulling in this library:

Will look at adding this after #554 is finalized and merged 👍
