I use secondary most of the time, it is not needed.
When I make mead, ciders, Imperials, I leave them in the primary for up to two months. Moving to secondary just helps them age and clear, or most likely I need my larger primary for my next batch to minimize blow off.
The only issue is racking it cleanly to bottle, I keg so I just crash chill it down to 36F for a week and rack it off if I don't use a secondary.
