People can follow ICDevs on the manage neuron topic. Every time the maturity gets >1 ICP we spawn the maturity to a new neuron that ICDevs owns, then we dissolve it.
I haven’t looked at the underpinnings of this yet to see if we could use Maturity instead of a spawned neuron(Can you split your neuron into one that holds all the maturity and one that doesn’t? I’m not sure).
I wish it were otherwise, but I have severe doubts that any taxing authority will view the use of maturity in investment as anything other than converting it to income, so jumping through hoops seems a bit overkill.
