Frame Blocks to declutter the Inventory

A simple Idee, Frame Blocks, and its variants (Stairs, Slabs, Walls, Fences, Fence Gates, Buttons, Pressure Plates maybe Doors and Trapdoors), that can take on the appearance of any block you right-click on it, consuming one of said Block and returning it, and the Frame variant, when broken.

This would drastically reduce the amount of different Block variants, freeing up Inventory and making every (Solid)Block, present and future, automaticly have a full set of Block variants.

Yes, I am aware this exists as Mods already, but i believe this would only benefit the Vanilla Game.
