Non-Stick Waxed Copper (All Variants) - Java Edition

Slime Blocks and Honey Blocks should allow the Waxed variants of the Copper Blocks to slide past, like it does with Glazed Terracotta. This would be beneficial because it would still allow these blocks to be pushed by pistons for waxing/oxidizing farms, however it would give another building option when working with slime blocks. Also waxing the copper would make it a slick block and therefore should allow the slime to slide right past.
