general question: do we need any sort of data migration?

[vishnumad]

@bangtoven Yeah, this will lose data for folks that were not passing in a storage object into the provider. I think we have two options:

• Write a migration that pulls the data from the MMKV default paths (Android, iOS)
• Or make it clear that this is a breaking change and if they were not passing in a storage object into the provider, with the new release they should pass new MMKV({ id: "mobile_sdk.store" }) in order to keep old data

[bangtoven]

@vishnumad gotcha. since we don't have that many client apps yet, i think we would just go with your second option instead of implementing+maintaining migration logic
