Although I started the original discussion on this feature, I want to go on record that I think it is a very bad idea. I predict it will not benefit price, not help anyone with their taxes, and it will further complicate an already very complicated system – in ways that may introduce unknown complications that will themselves have to be mitigated later, as happened with changing voting weights. Clever ideas on top of complex systems often seem like a good idea before they are put into practice.
Instead, I think the IC should double down on stability and correctness, and give the market a few years to show us, by real data, where the NNS needs to change with respect to maturity.
