Great explanation, very concise and to the point.

Even if you are just implementing a MVP, I always recommend at least the Single Database CQRS. It makes life much easier being able to apply transversal behaviour to commands or queries, like transactions or caching, even if you don’t implement the domain layer and access the database directly from the handlers.

Recently I made an article about the mediator pattern for C# to help implement this: https://medium.com/swlh/mediator-pattern-in-asp-net-core-applications-109b4231c0f8
