Thank you for your PR. Can you add some tests for this feature to prevent future regressions?

I've encountered this breaking change in production and created minimal reproductions that demonstrate the issue:

Before v10.9.0 (working): https://stackblitz.com/edit/vitejs-vite-cdqkbqje?file=package.json
Current version (broken): https://stackblitz.com/edit/vitejs-vite-hzsdf8sq?file=package.json

This change has been blocking our upgrade from @vueuse/integrations v10.7.2. Since it was released as a minor version update, we didn't anticipate breaking changes.

I came here to propose a serialization option and am glad to see it's already been suggested! The approach in this PR looks great and would solve our use case perfectly.

Is there anything I can do to help move this forward? I'd be happy to:

Test the PR in our production environment
Add test cases for edge cases we've encountered
Help with documentation

Thank you for working on this!

@matthewjumpsoffbuildings lets get this over the line! Would you be willing to add the suggestions?

@acrobid You can use pnpm patch command to test whether this approach works for you. I think we might merge this soon. But I think we will not backport this to older major versions.

@OrbisK @acrobid I pushed some commits attempting to apply the suggestions, default serializer, better typing etc

I don't have time to write tests right now, if someone else can handle that that would be good
