Starred Netherite Tools (need better name)

This idea is kinda complicated, but I have faith that the devs could handle it. You should be able to add a nether star to a netherite pickaxe (and maybe shovel and axe) to make it have a vein miner effect. When you shift and mine ores and stones, all nearby blocks of the same type would also be broken. This would make the ores' drops drop where the first ore was mined, and the xp as well. this would combine with fortune (maybe making the chances of multiple drops lower), and silk touch. This could be a treasure enchantment that feeds off nether stars, or where you add a nether star in a smithing table, or some such restriction. Using the vein mine feature would only take one duribility, but could be balanced by making the vein miner part show up as an enchantment, and making this enchantment incompatible with mending and/or unbreaking. I realize that this would be very overpowered, and that's why it requires a nether star to make, since you can mine for hours and get plenty of netherite and/or diamonds without fighting anything, but to get a nether star, you have to find a nether fortress, kill wither skeletons, and kill the wither. Plus, this would replace the beacon, if you did kill the wither.
