It could be fun to make creeper and/or ghast explosions break blocks as though they had silk touch to allow for player-less farms for silk-touch-only blocks.
This should probably also be accompanied by rules that can make creeper and/or ghast explosions have a 100% drop rate and another to stop ghast explosion fires (I can't remember if some of these are already implemented).
