>
> Excessive wrapping and tangled class hierarchy complicate migration of 
> discovery custom messages to the new message framework:
> {{DiscoveryCustomMessage}} is wrapped into {{CustomMessageWrapper}} 
> (implements {{DiscoverySpiCustomMessage}}), which in turn is wrapped by 
> {{TcpDiscoveryCustomEventMessage}} ({{TcpDiscoveryAbstractMessage}} 
> hierarchy).
>  
> *What can be done:*
> * {{CustomMessageWrapper}} (extends {{DiscoverySpiCustomMessage}}) can be 
> deleted, it is just a wrapper.
> * {{DiscoverySpiCustomMessage}} interface is redundant. Can be temporary 
> transformed into ordinary class (issue for complete deletion IGNITE-27778).
> * All {{DiscoverySpiCustomMessage}} inheritors can inherit from 
> {{DiscoveryCustomMessage}}
