I agree that having jar'ed plug-ins is of great value but is nested jars 
really an optimization? I might be wrong (haven't tested) but I doubt 
that any gain in performance, memory consumption, or even significant 
size on disk can be proven.

Of course not. My point is that the since the compiler fails to 
recognize nested jars, any downstream project depending on such plug-ins 
have to go through the hassle that I described earlier. I'm questioning 
why that is recommended and why it's considered good citizenship.

All bundles depending on jar'ed bundles with nested jars have this 
problem: https://bugs.eclipse.org/bugs/show_bug.cgi?id=147831
