When I get a change, Ill adjust the small prettification differences

[GeoffreyBooth]

Do any other runtimes support JSONC or plan to?

[RedYetiDev]

I know Deno supports it with its builtin standard library (https://deno.land/std@0.223.0/jsonc), but I'm not sure about importing

I'll need to check the other runtimes, and more about Denos imports

Blocking for the following reasons:

1. There's been no discussion of whether this is a good idea at all, much less something worth adding to core; and whether the best approach is via extending import as opposed to other alternatives such as a utility function.

2. Importing JSON is supported by browsers and there is a spec around it. I'm unaware of anything similar for JSONC. We shouldn't add import abilities for unspecified types. That is better handled by userland hooks.

2. That is better handled by userland hooks.

If #49704 ever gets revived, that could also facilitate this so users don't have to manually sort out something almost everyone wants.

nit... looks like some linting issues with these files (among other things there should be a new-line at the end.

I don't think this is a good feature to add either.

Additionally, the approach to strip comments from jsonc files is incorrect, check what userland modules do instead. Regular languages and all that..
