My example was only a theoretical example
The automation feature depends only on the features of a given plugin, so if the manufacturer don't support certain parameters for automation, you don't get them in your DAW.
There are global parameters like track volume, pan or MIDI velocity that are plugin-independent and therefor can be used system-wide.
Don't get confused by "dynamics". You could use MIDI velocity automation to alter the pure volume of a single sound, but what I mean is firing different sounds on different velocity values. BFD2, as an example, has instruments that are sampled with up to 128 different velocity-depended audio sample files for only one snare head trigger. The point is that the DAW itself would only alter *one* sample volume.
But BFD2 has also a real "dynamics" button for each instrument that could be automated on a track. If you don't see a wanted plugin parameter in the automation options of your DAW, then it's simply not intended to be there.
I think these information is not necessary good for the database, because it's 1.) very complex and 2.) it'll last not long enough and has to be updated very often.
