Note that syz is essentially based on Data.Data, which is no less "official" than GHC.Generics. (The compiler can derive Data with -XDeriveDataTypeable.)
I am not sure what your primary concern is. In case you are concerned with the ease of deriving generic instances, almost every generics library out there, including traverse-with-class, provides a TH function for deriving the necessary instances. You can write a zipper based on GHC.Generics, but it won't be a straightforward translation of syz (nor would it be a trivial undertaking).
