I suppose one could, it's easy to do in some cases like in JarFile.

Given that Enumeration is a legacy thing time could be better spent on adding Stream returning methods, which already exist on JarFile/ZipFile. 

Contributions will be warmly received for Stream returning methods on ClassLoader, NetworkInterface etc.!

Right :-) works until it doesn't.
