Minecraft wiki entry for Seamless_Stone_Slab, associated text: The use of a single texture on all sides is a trend which can be seen in many other extreme metadata variants: wood, which also eventually became obtainable intentionally, pistons and sticky pistons, hay bales, and Bedrock Edition-exclusive cases of chiseled quartz blocks, quartz pillars, purpur pillars and bone blocks. (Several other extraneous metadata variants, such as those of lit and unlit furnaces, dispensers, droppers, jack o'lanterns and pumpkins, the last of which also was reimplemented intentionally, used their texture on four sides, due to having a dedicated top and bottom and most being able to face in four directions.)
