I would say it is fine to secondary ANY beer if a person wants to. One doesn't have to, but they can if they want. As with any hobby there are people who enjoy them at all kinds of levels. Some folks are more hands off, others just can't resist playing with their beer. If someone has good sanitation and can transfer the beer with minimal splashing (ideally into a purged vessel) then I see no problem with using a secondary vessel for aging and clearing, again for ANY beer style.
It might not be worth it for a Hefe or a Wit, but if that's what someone wants to do, I say, go for it. Or one could skip it for most beers. That's fine too
