Ooops I did mean to leave one comment on this...

The behavior is semantically correct, should note it may or may not lead to 'vexing' behaviors for consumers that are inadvertently dependent on the behavior (e.x. repeated externally fired messages and they don't have proper guarding.

tl;dr- Good mention in release notes would be nice, I know I've had to write code to get around this in the past. <3

We'll try to address this on the front-end with akkadotnet/akka.analyzers#104 - but yes, we'll also add an upgrade advisory for this issue in v1.5.31
