Copper buttons in 1.21

I think copper buttons would be awesome. Maybe they could have a really short time to pop back out (shortening the time the signal is output) but that time could become longer when the copper becomes rusted. I think a unique button like this would be great, and a more functional button made out of a less common resource would be really cool too, especially considering how much copper stuff is being added in 1.21, making it a notable resource like the rest of the ores. This would also be very great for redstone mechanics as well as maps that test player knowledge.
