It's possible that the reason there was es.symbol is that when polyfilling JSON.stringify we also have to polyfill symbols. In that case, this definition should be
| stringify: define("json/stringify", ["es.json.stringify"]), | |
| stringify: define("json/stringify", ["es.json.stringify", "es.symbol"]), |
Let's wait for @zloirock to see this PR before merging :)

It's not a bug or something like that. In early versions of core-js@3, JSON.stringify logic was only in es.symbol module to fix JSON.stringify with symbols. After that, many other fixes of JSON.stringify logic, well-formed unicode, JSON.rawJSON support, etc. were added and the main part of JSON.stringify polyfill was moved to es.json.stringify.
For modern core-js versions, es.symbol here is not required, however, it could break compatibility with early core-js@3 versions.

I think it's removed because it seems to default to version 3.0. I noticed this while testing the package.

This entry is available in 3.0.
IIRC it could be removed because of the order of modules in the array of dependencies - here the first is es.json.stringify that wasn't in 3.0 - however, it does not mean that core-js-pure/features/json/stringify is not required.

It checks getModulesByVersion (something like that, which references a JSON file with that metadata) in core-js-compat and es.json.stringify is not mentioned under 3.0. I think that's why.
For pure I believe it only checks the first entry in the array since a pure import will fetch its own dependencies.

Yes, because JSON.stringify polyfill was only in es.symbol and it was exported in core-js-pure/features/json/stringify. Which is what we're talking about above.

I think that the way solving of this issue is wrong - it's better to allow passing entries for exclusion, like |
|
This PR is to fix the exclusion :D I think perhaps the library should default to using the latest version of core-js rather than 3.0. |

Any update on this? |
