Our preference is to avoid this kind of automatic connectivity. While it has its advantages (e.g., it makes circuits, especially logic circuits, appear cleaner), because modern designs frequently use a number of power supply rails and grounds as well as power supply bypass and treatment schemes, it can create schematics that are confusing at best and impossible to draw at worst. | Our preference is to avoid this kind of automatic connectivity.
