Sumps add complexity, and are not necessary on any tank, reef or otherwise.
They do have their advantages though, and I would choose to run one on any reef over 20 gallons or so, below that I don't bother.
On a freshwater planted tank I would never plan for it - if my tank already had an overflow then sure - or maybe the "sump" would just be an expansion of the main tank. Another light, more plants and fish....
