<br>
as I am trying to simplify current entry wrapping and distribution code,<br>
I often find that listeners can get wrong previous value in the event,<br>
and it sometimes forces the command to load the value even if it is not<br>
needed for the command.<br>
<br>
I am wondering if we should change the previous value in events to<br>
Optional - we can usually at least detect that we cannot provide a<br>
reliable value (e.g. after retry due to topology change, or because the<br>
command did not bothered to load the previous value from cache loader)<br>
and return empty Optional.<br>
<br>
WDYT?<br>
