I think this is the root cause of your questions. You say "portage has no way to know the difference" - who says that is true? Did you assume it? Why should virtual packages behave like regular packages? They are even in a different category to everything else. Treating virtuals just like regular packages doesn't make sense to me. Treating them as variables does make sense - they get expanded into lists of possibilities and when the graph is resolved, the existence of the virtual goes away. But that is speculation on my part. I think if you get an authoritative answer to that question, then we can continue to examine the behaviour.

You'd have to ask Zac what he intended. I can easily see the code being written such that emerging a package and updating world use completely different code paths, simply because they must evaluate things differently with subtle differences. You'd really have to read the code to get proper answers to your questions.
