[Suggestion] Make stairs directionally powered with redstone

[CollidaCube]

When a block is powered with redstone, it would power a redstone component in any direction through that block. I think it would be cool if you could power a stair and it would only power the faces that fully take up the face (including bent stairs). It'd be awesome to control the flow of redstone in compact areas. I hope i explained this sufficiently? Mumbo explains this idea better in his video.
