Since the introduction of the PackageManager PSR-0 support is there for 
Flow and Composer Packages. But it does not help that much as the right 
package path for the classname has still to be determined. See [1]. And 
copying class files into the right folder structure deterministic 
resolving is imho a no go. It introduces issues of its own, like when to 
invalidate the copies and recopy them?
