Serializable `ProceedContext`

[john-giordano-mongodb]

Hi - Based on my reading of the examples in this repo, the only way to carry ProceedContext between calls is via an in memory store (code). This pattern is not supportable from a stateless app - the context need to either be saved to a shared data store or sent back to the client side. Either of these options requires a serializable context.

Am I understanding the examples correctly. And if so, is this a feature that would be considered? It looks like there was a prior effort to make several of the other models serializable
