Is there a way to register a cancellation listener on a coroutine scope without doing suspendCancellableCoroutine so that if the scope gets cancelled I can close my DB statements

You can use try-finally/`.use` ext to close resources.
But if you need a scope callback - you can take Job element from scope and then use invokeOnClose

I ended up spinning up a new coroutine in same scope and then hooked up suspendCancellableCoroutine

if scope was cancelled before you launched it - your resource will leak, because coroutine won't be even launched (for this case you need to use non-default start option - either Atomic or Undispatched)
