It's a silly syntax and breaks compatibility. This is valid syntax:
-net tap,fd=3,fd=4
In this case, it means 'fd=4' because the last fd overwrites the first
one.
Now you've changed it to mean something else. Having one thing mean
something in one context, but something else in another context is
terrible interface design.
