Making sure no pokes end up getting stored on a backup, or in a cache, or temporary directory, could be tricky. Having to only have one thing, stored specially, to clean out might well be easier to organise in a big already existing framework.

Then, to ensure that this app has the privacy that people expect from an app of the ephemeral kind, they are baking in additional precautions. In this case, a key that gets destroyed is the precaution. I am not an insider, this is just a guess, etc.
