The NNS is verifiably the controller of the neuron (the permanent, formal controller than can never be changed). Note that this is the same for NF neurons, and that’s why you see statements like this in the documentation.
neurons created for NF participants are controlled by the NNS
Also note that two prominent DFINITY team members are on the D-QUORUM co-founding committee, involving back and forward discussion before setting D-QUORUM up. The founding committee is also composed of members of Synapse, members of CodeGov, members of CO.DELTA, dev team engineers from prominent projects including WaterNeuron, Toolkit, TAGGR, the list goes on.
This statement should be balanced against the actual D-QUORUM goal and co-founder commitment →
The NNS can boot the Neuron Management followees whenever needed, and this will be welcomed.
Back to the Point - Slashable NP Neurons…
My point is that nothing needs to be done by the NNS to support the D-QUORUM mission. Simply by facilitating slashable NNS-controlled neurons (with maturity cascade), elected proposal reviewers will automatically begin receiving D-QUORUM maturity. Then we can get on with the business of increasing the D-QUORUM neuron stake, for which there are numerous plans.
I understand that you’re hesitant about this idea Wenzel. D-QUORUM is about supporting competition in the proposal reviewer community. This is sorely lacking, which serves existing proposal reviewers well. Rest assured that this initiative is designed with best intentions for the network as a whole.
