Event sourcing could be a great architecture for general purpose applications - if we had good frameworks and specialized event stores built for this purpose.

Event sourcing could be a great architecture for general purpose applications - if we had good frameworks and specialized event stores built for this purpose. Some features that would be needed: * Automatic , schema based event and aggregate versioning * A combined event and aggregate data store with ACID guarantees, schema validation and indexes * event migrations (so you don't have to carry around old event versions forever) * Event stream migrations that allow re-writing streams for purging data, gdpr cleanup, etc * Copy on write based stream clones that can be used for testing with production data As it stands, such a solution is nowhere to be seen. So you have to cobble together a working system with lots of custom work , which often ends in a complete mess.
