Sorry, I’m not trying to be annoying. I just want point out that @bjoern has already described how a canister can control a neuron today in this post. which is what inspired this proposal. As you’ve said before, he is the foremost expert on the matter and works at Dfinity.
This proposal aims to make the development of this capability simpler. The only thing preventing it today is the complexity. So I would classify it as a matter of when and not if.
