Unbreaking IV for gold tools and armor

I believe that gold tools are heavily underused because of their immense speed. Not to mention, gold armor is basically required if you want to explore the nether after 1.16. To make gold tools and armor more usable, a propose the idea of giving gold tools and armor the option to have unbreaking IV. These would make the tools and armor more used, considering that diamonds are hard to come by in the early game, and gold isn't used as much as it should be. A slightly more far-fetched idea would be that gold armor could offer more protection in the nether, as you need it to not get swarmed by piglins, and gold in real life is harder when it gets hot. These changes would make gold more used as a tool, as an armor, and will give you another reason to go mining for gold.
