Redeeming miles for the annual fee is technically a part of the Chase Pay Yourself Back Program, covered here:
Pay Yourself Back - Sapphire Reserve & Preferred, INK Preferred & Plus, UA (2024-)
time_stamp - I added your report to the wiki there. Thanks!
Just to clarify, the redemption rate on the standard Business card without club access is 1.5 cents/mile... I'm not sure about the Club version and haven't seen any specific reports on it.
