Why? I just don't find myself doing too much JSON manual editing. A few config files and such. Occasional editing of a server response or call for testing.

I'm basing this on the assumption that the desire for trailing commas is making editing easier and reducing noise in diffs.

Just curious if there are niches where people are spending a lot of time manually editing JSON or if the use case is something else entirely.

I love them in code, despite initial resistance.

The use case for me is JSON blobs (mostly configuration files like package.json) that are checked into version control. Same motivations - reducing line-oriented diff noise.
