Upgradable armor and tools!

In the update, 1.20 it added new ways to customize your armor called armor trims, I was super excited when I finally got to change the look of the armor. But I made this post to just give you guys ideas for the 1.21 or a later update. Redstone armor trims giving off light for a few minutes when you stand on a block of Redstone, or gold armor trims making piglins passive but still letting the brutes get mad, or netherite armor trims adding knockback resistance or fire resistance, you get the idea. But if you want to, I think making tool upgrades would be an awesome idea, just like we have the Upgrade Template, we got the tool upgrade template, let's say we have an iron sword with lapiz lazuli upgrade (you should not be able to stack them) when you defeat a mob you should get a little bit more xp but not too much. I think the community would also like Eco shard trims too (maybe to get extra protection from the sonically charged shriek that comes from the warden maybe?). Plus speaking of eco shards I think the statue in the very center of the ancient was a portal that no longer works but just like how flint and steel works maybe adding a second item for the eco shard to maybe light the portal to at least give it more of a use?

P.S. I like the 1.21 update looking good so far, liking the trail chambers and dyeable wolf armor!
