Samsung Android Siging keys leaked- SmartThings integration improvement opportunity?

[Participant]

Samsung’s Android app-signing key has leaked, is being used to sign malware

I wonder if this would provide an opportunity to make a version of the SmartThings app that could facilitate performing MITM the setup and cut out Samsung’s cloud? Similarly, if they lost this, what about keys for the Tizen android fork in a lot of their SmartThings appliances.
