Yes, because most of those noteOn()/controller() calls have higher-level
semantics.  I would wrap a scenario-specific library with "turnOnLights()"
calls or something, and those would have implementations that translate into 3
bytes of data.  We shouldn't need to have app libraries just to hide the
details of the funky boilerplate, and I don't think in general the note on
message vs controller semantic is a necessary one; you use what you need at
that point in your app.  In some cases, you'll be writing a learning/remapping
layer anyway, that might need to change what calls you're making.

Plus you're suggesting wrapping ANOTHER layer around what I'm already saying I
think is too many layers.  :)
