Without deciding an implementation, I just want to make it known (I think)
this feature is a must-have.

I want to also make it clear that these normalized outputs can be tied to
naturalized inputs.  I don't know if this warrants a whole different
mechanism or not.  What I mean is:  Think of these controller plugins like
MIDI controllers.  They can control any knob, and something must do the
mapping of normalized range (0-127 in MIDI, 0.0 to 1.0 native?) to
whatever the receiver's range is.

I'm beginning to think that these controller plugins don't just use a
parameter-out, since there is so much metadata and routing that needs to
be handled.  Maybe the indicate to the host that they have a controller
output and the host is responsible for treating it like a MIDI controller
or whatever.

This lets us have much higher resolution (sample rate, if we want) for
controller plugins which can control just about anything.

The topic "Control I/O" now has 1 requirement, and that requirement is
dubious under that heading.  Maybe the heading should be "Controller
Plugins" or this req should just be somewhere else?

Should I update the "More..." section to include these further thoughts?

I'm going to see my mom and family - it's been too long. :)  Ahh, lazy
days.
