Standardization of shapes of blocks/stones.

When I talk about standardization I mean that all solid blocks (prismarine, quartz, stone, bricks, endstone, deepslate, blackstone, etc.) should have all the variants of blocks (slabs, smooth, wall, stairs), which, for example, is very well done with wood.

I do not understand why quartz or dark prismarine do not have walls, or that the endstone or prismarine do not have smooth blocks (like smooth quartz). Besides some blocks like stone don't have tiles or polished variants.

I understand it's a lot of blocks and perhaps in some cases it is a matter of design so that each block has its personality, but this already happens with its own textures and colors.

It would be great if we could have all those varieties. Personally I love walls and tiles, and many blocks do not have :c

What are your opinions on this?
