Why CancellationException is treated apart, and why throwing? Will it make the app crash?

CancellationException in general won't make the app crash.
When launch gets a CancellationException, it just gracefully stops executing.
When async gets a CancellationException, it just gracefully stops executing and other coroutines calling await() will get the cancellation exception.
The only case when it may crash the app is if it is directly thrown inside runBlocking, since it has to run in non-coroutine code.

Isn't it ok to let the CancellationException go to OtherFailure then? it won't change anything in the execution flow, but we'll loose the error in the UI if not posting to viewEvents

It's technically not an error, the task has just been cancelled and this will only happen if the view model has been cleared, so if the UI has been destroyed.
But yeah it doesn't make much of a difference I can remove the special casing.

Yes I wasn't thinking about this specific case, but more generally. We can get a cancellation if some suspend got cancelled by any inner stuff. By the way, we still have to be able to cancel all session coroutine (clearing cache/logout)

That complicates things..... Is that the only time when you cancel all sessions coroutines?
In the case of viewModelScope the coroutine would already have been cancelled before user logs out or clears the cache, no?

I guess for most of the cases it will be ok yeah

Thanks for the update.
I will fix the conflict and merge the PR (EDIT: there are no conflicts, this is on another PR).
We have to think about the other applications which uses the SDK, and which are maybe not ready to use coroutines. Maybe for them we will create a project which converts coroutines to MatrixCallback. But for Element and its forks, we think it's a great improvement of the SDK API :)

Pull Request Checklist
Would do a big PR but this will be easier to review.
Also each endpoint needs to be checked to see which dispatchers it should use so it's best to keep it small.
