Certainly, but the main benefit of such a system is that you could
write wrappers for dependencies.

Say you use two libraries A and B. A has a requirement for "Foo 
XML parsing", such as provided by the library FooXML_1.0.4.jar, 
while B has a requirement for "Bar XML Parsing" as provided by
BarXML_2.3.jar. Rather than include two XML parsers, you can
just write a small wrapper FooBarWrapper.jar which provides
the "Foo XML parsing" functionality, implemented by calling the 
BarXML implementation.

Sure, there are dangers here in clients relying on implicit 
behaviour from a given library, but at least you'd have the
_option_ to consolidate similar nodes in your dependency 
graph.
