Looks like this example doesn't pass type checking anymore. Why do you change the specifier here to the stable version?

[kt3k]

Sorry for the delay in review, but I don't think we can merge this change as this doesn't pass many of existing test cases in stringify_test.ts.

We plan to replace stringify with unstable-stringify in the future with some stabilization process. This makes unstable-stringify incompatible with stable stringify, and that makes future stabilization impossible.

[kt3k]

Closing as it's stale and also the suggested interface is not compatible with the existing stable stringify
