Steel/Bronze Alloys in Vanilla Minecraft

I know a lot of people have had this idea, but I will expand on all of them. Mojang made room for new ores in the past, so hear me out.

Steel isn't an ore that spawns, you would have to combine iron with coal to get it. It would make tools & armor that are more durable/efficient than diamond, but less so than netherite.

Bronze is similar because you have to combine two ores to get it: copper and tin. Tin would be like copper in the way that it's a naturally spawning ore you smelt and can make blocks out of, but not much else: you could use it to create whatever gizmo Mojang comes up with to give it another purpose, but no tools or weapons. When you combine it with copper, it creates bronze, which would give copper it's first *useful* use because you can also create tools & armor with bronze. They would be more durable/efficient than iron, but not more than diamond.

You use a new workbench, the smithing forge, to forge alloys. Too high-tech, Mojang? Then use the smithing table instead. You would need smithing templates to make these new alloys. You could find bronze templates in pillager outposts and steel templates in woodland mansions, or both in mineshafts but you would be less likely to find steel templates. The templates should not be duped with diamonds, but with copper for bronze and iron for steel. You need a template to make every ingot, but tools/armor have to be CRAFTED with alloys, not upgraded. You could upgrade like neth, but that's too easy to get in my opinion.
