 NOTE: we should consider providing a command processing implementation based on Apache Camel once this concept is approved and we migrated already a couple of services. They are specialized for exactly this kind of use cases and have more dedicated people working on it's implementation. Could give more flexibility without us needing to maintain code.

@@ -52,7 +52,6 @@ Please make sure to always follow this package structure pattern:
 - `handler`: contains all command handlers
 - `service`: contains business logic services
 - `mapping`: contains MapStruct interfaces
-- `middleware`: contains middleware related to command processing; I am not expecting that we will need any of this during the refactoring process
 - `security`: might contain later so called Spring Security "authorization managers" for more complex use cases
 - `serialization`: technically we should not need this package anymore after we are done with the refactorings; in theory there could be very complex data structures that are not easily digestable by Jackson; for those case we could still use this package to add de-/serialization helpers (Jackson provides a proper API for this)
