Your original link points to the Vanilla add-ons, and I doubt that there are any Vanilla 1.12.1 add-ons that work on the modern WoW API, which is why there is a massive movement to port everything over to Classic (even most BFA add-ons need to be slightly adjusted to work on Classic).
Yes. /facepalm. Link in other post fixed. Thanks for the spot.
