Enable includeLibs also for USER and COA objects
The TypoScript object USER does not support the includeLibs property. Loading an accordant PHP class the library gets added to the global context and included there - no matter if it's really required or not.
This is somehow a waste of performance and memory.
The solution is to enable "includeLibs" also for USER objects and only load the PHP class if it's really required.
