I find a village that had spawned with wooden planks as the path. Images attached:

that's because the paths were over water.

Works as intended. If the path would go through water, it is made of planks.

This is implemented so that the village houses are actually accessable for the villagers.

Wood replaces water, grass path replaces grass blocks.
