That way, I could swap out devices or distribute my code to others, without having to worry so much about hardware integration. That sounds valuable from my personal perspective.

It is valuable, but has the downside of coupling to a closed-source third-party cloud.

Perhaps a better goal would be to encourage a public collection of CoAP- or OSC-based interfaces for these various end-point devices.

Crowsnest is encouraging people to write and submit such end-point code; better that it be workable with OSS infrastructure.
