Year Milestone Capes

I think it would be really cool if there was specific capes added for different milestones based on how old your minecraft account is. Not every year but possibly at 5 years, 10 years, 15 years etc so the capes are still rare but the older minecrafters can be rewarded for sticking with the game for a long time/joining early on. The design could be just the number of years on it with some color variation or maybe they're all the same design but different colors entirely for example 5 = bronze/iron, 10 = silver/diamond, 15 = gold/netherite. It could also just be the same cape but it gets more completed or worn as each milestone is hit.
