Definitely a no for this proposal, veANC is the way to go.
No earners will appreciate having 25% of their yield paid in a volatile asset, and savers will not appreciate the 5% ANC value requirement to receive 100% UST yield, also it eliminates the elegant aUST composability system and makes calculations much more complex.
This proposal defeats the purpose of a simple savings product and will scare away normies and hinder mass adoption.
