It depends on the design. Sometimes I do a board where all of the  
74XX logic runs on 3.3V. In that case, explicit power is a  
distraction, so just connect the incoming power to a Vcc symbol and  
make a note. Other times, each individual chip has a resistor on its  
power pin to protect against radiation-induced latchup, so explicit  
power pins are essential. And VLSI design gets you into a bunch of  
other issues.

gEDA is a flexible toolkit, not a one-size-fits-all solution. Hurray!
