I'll throw out the most important reason that hidden nets (e.g., Vcc/GND pins) on symbols is bad: Power and ground connections are a critical part of the circuit design but would not be visible when looking at the schematic! You would have to click a symbol and bring up the attribute editing window to see to which net power and ground are connected. If you print the schematic or view it as a PDF, this important aspect of design is lost. Certainly there are other important attributes that are often hidden, like “footprint”, etc., but footprint is actually less of a concern for the schematic, and more of a concern in other workflow phases (i.e., layout, or preferably a separate future process to separate footprints from the schematic...).
