ME cache is case sensitive for page names and excerpt names but ME Include is not
Cache inconsistencies can result because the ME cache is case sensitive for both page name and ME name.
However, Confluence is not case sensitive for page name and MultiExcerpt Include is not case sensitive for ME name.
This leads to cache inconsistencies that require cache flushing to work around them.

Fixed in 5.4.3
Admins can opt out if they need time to fix references in MultiExcerpt-Include that point to the wrong name (considering case-sensitivity). For example, if their excerpt is named "Test" and they included it by using "test" in their MultiExcerpt Includes then they need to find them all and change them and THEN they can enable case-sensitivity.
It is important to use case-sensitive includes:
so that migrating from Server to Cloud is seamless
so that "Find Includes" works
so that the cache works
