I'm investigating possible migration of Decompose to `SavedState` and `ViewModelStore`, since they both are now multiplatform. However, I noticed (correct me if I'm wrong) that the actual serialization of `SavedState` to bytes is only possible on Android. On all other targets the `SavedState` class is just a `Map&lt;String, Any?&gt;`. My question is probably for folks from Google and JetBrains: are there any plans of supporting the actual serialization of `SavedState` on non-Android targets? Or if it's already possible, I would like to learn how.

Hey Arkadii, long time no talk!

You're right. Currently, serializing `SavedState` to bytes is only supported on Android. It’s definitely something we have discussed and would like to have in the future, but no ETA. I just realized there’s no public ticket for that, <https://issuetracker.google.com/issues/new?component=878252&template=1442003|would you mind filing one>?

Also, while `SavedState` is KMP-compatible and is integrated with CMP, CMP doesn’t actually save state on non-Android platforms (yet). JetBrains is the best people to speak to that part. cc: <@U04RLA9DQ6A>
