I think it only matters if we define ramped events. It's there now to
differentiate from ramped events, mostly.

That's a separate issue. My first inclination is that this is the plugin's
choice to implement. Right? Wrong?

Well, we should probably put a requirement it if we do define ramped events.
If we decide not to do ramped events, then maybe it is extraneous.

I added a small bit of text saying that a (SET, NOW, Instantaneous,
whatever) event might actually be subject to a fast smoothing. This is
different than ramped events, though. A ramped event is more like saying
"Mr. Plugin, please set parameter X to value Y over the next Z samples".
The plugin can then smoothly interpolate the change, rather than receiving a
series of closely spaced discrete events.
Now - do we need something like that? Doesn't AU have it?
