Correct me if I'm wrong, but these days, isn't the absolute cheapest way to use an ATtiny MCU or something? As much as I love the idea of discrete components and jellybean logic chips, it seems MCUs do it far cheaper in the end...

That's only true if you have high enough volume, and can write off the one-time costs e.g. Microchip PIC10F200 can be bought from Microchip Direct for as little as $0.34 USD each, preprogrammed with your code, provided you are ordering more than two reels at a time (3000 per reel).   If you are only building 10 units, you are probably looking at half a day to write and test the debouncer and program all the chips, which could easily add $20 to the cost of each unit, by the time you've figured in wages and business overheads.
