There are lots of ways to implement it. The problem is that one of JSON's strengths is its ubiquity: every language under the sun has half a dozen different battle-tested parsers for it. Clients and servers and everything in-between have first-class support out of the box. You can even paste it directly into JavaScript as valid code.

If anybody short of a standards body tries to expand the spec, you lose out on most of that.

i think you can possibly define how you want to use json for a configuration file; json by itself is not much more than javascript objects/maps, defined as a data format. I frankly don't think that you need to be too pious about standard compliance if dealing with a cofiguration format for your application.

And without comments or optional quoted keys single quotes or trailing commas, which makes editing by hand more work and IMO less readable.

Editors, for one, will be an issue
