Well, the controller is a single physical device and as such, it feels like
it should be represented by a single object in Pd. For example, I could need
to connect four controllers at once, and I would like each to be represented
by its own object.

Also, each object needs its own context (the connection to the device), so
for a single device, the [in] and [out] objects would need to share that
context. Otherwise, I would need to connect each [in] and [out] separately.

Well, that's true, but in my case it's a bit uglier than that: not only would
I have two distinct objects, but each would be in its own distinct module.

The [in] object would be an instance of [hid] (or [hidio]) and the [out]
object would be from a new external dedicated to controlling LEDs on Linux.
Because of this, it would require each input and output to be configured
separately.
