Description
Currently events emitted from InitChain handlers are deferred until the first block by serializing them into storage. Even though event changes are otherwise not consensus-breaking, handling them like this makes them so as the initial state root depends on their serialization. It would be great to change this to avoid unexpected breaking changes.

Research direction
Start by tracing the InitChain event handling, deferred serialization into storage, and the initial state-root computation. Determine how event serialization currently affects consensus, then define and test a design where changing those events does not change the initial state root or create unexpected breaking changes.
