[MC-165977] Explosions combine block drops and drop them at the wrong location

The bug

Explosions now combine block drops and then drop them randomly at the position of any destroyed block, possibly not even the same block type.

How to reproduce

/fill ~1 ~ ~1 ~5 ~ ~5 orange_wool

/fill ~1 ~ ~1 ~5 ~ ~5 orange_wool

/fill ~2 ~ ~2 ~4 ~ ~4 cyan_wool

/fill ~2 ~ ~2 ~4 ~ ~4 cyan_wool

/summon tnt ~3 ~1 ~3

/summon tnt ~3 ~1 ~3

Why exactly has this been resolved as "Won't Fix"? Could a reason be provided?

This was done for performance reasons, with pre-stacking of the item entities. We'll change it so drops appear at the position of a correct block type, but note that it'll still not be "fully correct" - a stone stack will drop from a stone block, but they will still be able to merge over larger-than-usual distances. You could say an explosion is a chaotic event that throws blocks around, I suppose.
