This is some next-level engineering discipline quietly knocking out 30+ intricate TODOs over five years, culminating in a clean transition from legacy to descriptor wallets and from bdb to sqlite. The patience, foresight, and long-term commitment here is honestly awe-inspiring. It’s a masterclass in how to evolve critical infrastructure without breaking users or trust. Core devs rarely get the spotlight, but this is one of those moments that deserves serious respect.
