Grimstone revival?

When deepslate was first implemented, it was titled 'Grimstone' and although I prefer deepslate as a name, it sounds cool and there should be a new type of stone called Grimstone that generates uniquely, has it's own building set as bricks or a polished type and maybe has an actual use such as maybe a unique function that makes it useful in redstone or maybe it can craft something that's useful in redstone. I hope this gets added although it's just an idea not something that's really necessary. Also mojang if you have a new redstone block idea but don't  know what it should be made of, maybe give this idea a try?
