No, that is what I meant.

Its not explicitly supported by the API, its just a parameter that can be
stored along with the others.

My experience is thats its not that much of a problem, the only problems
arrise when you have things like compressors and the user picks a mono
compressor and two get instantiated on a stereo stream, instead of picking
a stereo one. That could be solved with better hinting.
OTOH I agree with you that dynamic port creation is powerful. I haven't
though about how much I want it though.
