Agreed, I really feel JSON5 should just be the default standard. But the fact that it's still not means it can't be used in a bunch of places where it would be an obvious improvement, for example, in package.json files - and fwiw I don't understand the NPM team's objection to using it.

As long as the file extension changes to align with the format, that sounds great. There are far too many abuses of .json that allow comments, trailing commas, etc.
