While looking at #6194 during Regen Sync call I discovered that data serialization is implemented on the storage level and has tight coupling with the app layer. I propose to decouple that: #7174 (Move the serialization layer out of the IAVL and enable clear interface between the layers: app, storage driver, storage engine.)

@aaronc @clevinson A little more description of what this work will enable at the high level in the summary would be helpful.

Linking these meta issues to the decision making and priority protocol would also be helpful.
