Updating Redstone mechanisms using copper

a copper repeater, it will have a lower delay than a regular one, this will help copper become more useful, in real life it is used in electronics, so why not implement it in redstone mechanisms, I am sure that if this topic is developed, it will give a new breath to redstone mechanisms, it will also be possible to use a copper block to transmit a redstone signal upwards with a small delay, so that this method of signal transmission is not unbalanced
