This might sound like a feature request and it could be an intended feature but it doesn't make sense that wearing armour with a gold trim should aggravate piglins.

Steps to Reproduce:
1. Create any non-gold armour with gold trim on it

2. Go to the nether and find some piglins

Expected Result:
The piglins "shouldn't" aggravate

Actual Result:
The piglins start killing as normal.
