I really dont understand where your coming from with this. There are
allready several LADSPA plugins that take control data from audio ports,
its not an unusual thing tho do. This hint would reduce potential user
confusion if anything as single stage plugin appliations would stop
presenting them as audio ports.

My main concern abou htis hint is that it artificially introduces a
distinction that isn't really there. Its fine as long as no modular host
ever prevents me form wiring an audio output to hinted continuous control
input or vice-versa.
