NNS Governance canister feature request: list_neurons by subaccount

Maybe we can get the lads at Dfinity to look at this again, there seems to be time to look at ListNeurons now:

ListNeurons API Change - Empty Neurons

We’d like to propose a change to the behavior of the list_neurons canister method in NNS Governance. Background: Empty Neurons Neurons can become empty in one of the 2 ways: (1) merging neurons - the source neuron would become empty (2) disbursing neurons after they are dissolved (neurons spawned from maturity also fall into this category). Such neurons can be “revived” by staking more ICPs, and they still contain some records such as recent ballots, but beyond that they are not very useful. In…

Request for Feedback on Governance: list_neurons pagination API

Context The IC Protocol limits message sizes to 2MB, including responses. Some users need to retrieve over a thousand neurons (typically empty) for various reporting purposes. They are currently unable to list them with this API because of these message size limits, as the responses would be over 2MB. While there are workarounds, it was determined that adding paging to this API would allow it to scale better into the future, and prevent wasted computation that results in undeliverable message…
