Lack of roundtrip means it's already broken and loses data, so upgrading to just the potential of a break is a marked improvement worth paying for

Can't lose data which you don't have and in this case there are no comments in json!

If you close your eyes, the data doesn't disappear! Of course you have the data, it's in the comments, and the original comment explains how it got there

If someone classifies comments as data then I'd say someone needs to upgrade data architecture chops

Yes the comment free spec forces to normalize what would be comments into data spec and it is frustrating to put more effort into things
