The bulk update request #4545 is pending approval.
remove implication micro_on_macro (27) -> size_difference (343882)
create implication micro_on_macro (27) -> extreme_size_difference (15908)
Reason: extreme_size_difference just has a description overhaul to clarify it, and it already implies size_difference. I believe it'd be more fitting for pics tagged micro_on_macro.
