Maybe there is no first-class support in the main opus encoder for object based audio, but as I've said above you can encode arbitrary matrices, so you can encode arbitrary positions for channels. That's enough for stationary objects. Moving objects, I'm not sure if Atmos supports them, can't be encoded in a single opus stream, however one can chain multiple opus streams after another. I don't think you need high time resolution for moving objects, something like one stream per 100ms should be enough, 10 per second. So in theory, opus can get get very close to object based audio, even if the encoder right now only does ambisonics.
