The way that GetAvailability is implemented is irrelevant - e.g. don't test the
private methods. Just test the single public method, but choose test cases that
would need to trigger each code path (e.g. commands API for manifest, bluetooth
for permissions, etc etc).

see comment in that other file. If GetAvailability returned a (channel, version)
tuple it'd be less magical and easier for the caller to intepret.
