Hello. Here to provide a closing response on this feature request.
We have introduced a Workspace property that can alleviate this issue in out announcement here New Player and Character Destroy Behavior
As communicated before, this currently enables the behavior on servers and not on clients as generally servers had a bigger issue with memory leaks from characters and players, seeing more of them over a longer period of time.
We will explore improvements in the future, including reports of server player destroy not being correctly replicated.
Unfortunately, we were unable to follow our timeline and make this setting a default as many experiences were not compatible with the change.
We plan to return to it and explore a less impactful default option in the future.
As always, developers still have signals they can use to destroy characters and players on removal.
