There was a problem hiding this comment.
So the decision table for this check looks like this:
| case | rate |
|---|---|
| 0 → 0 | reset |
| 0 → ≠0 | set |
| ≠0 → 0 | reset |
| ≠0 → ≠0 | reset |
Is that intended?

!= 0 -> 0
also leads to storage_clears ++ which is later handled by inter-vm rules

This will charge for setting already initialized storage entries less, also will track refunded (storage set back to zero from non-zero)
