I've not heard of any vets suggesting this. OFA prelims, perhaps, if you are considering any venue of competition, but otherwise, unless there is reason to suspect a problem, I would wait until 24 months to take OFA radiographs.
From "Canine Hipe Dysplasia Part III by John Cargill MA MBA MS & Dr. Susan Thorpe-Vargas :
In humans, the most popular and reliable palpation maneuver used to identify congenital dislocation of the hip determines the presence or absence of the Ortolani sign. "A positive Ortolani sign confirms the diagnosis of coxofemoral subluxation in newborns prior to development of clinical signs or radiographic changes." 8 Many veterinarians feel that the techniques have too much subjectivity and variance to be of much use. Nonetheless, the Ortolani sign still figures prominently in the literature. 9-14 Animals to be examined must be anesthetized past the point where there is still a palpable response. Two basic approaches are used: dorsal recumbency and lateral recumbency, with dorsal recumbency being preferred for large dogs. Downward pressure is applied down the axis of the femur until the femoral head subluxates. The leg is slowly abducted while holding the stifle firmly. If the joint is loose, a distinct clicking may be felt and in some cases will be audible.
Other palpation methods have been proposed by Barlow and Bardens. 15,16 Barlow’s Sign is essentially the first half of the Ortolani Test. Downward axial pressure is applied on the femur without abducting the leg. The Bardens’ Test places the dog on its side, and the leg is held perpendicular to the spine. Lifting pressure is applied to the femoral shaft without abduction. The examiner’s finger is placed on the greater trochanter. Any movement of the finger by more than one-fourth inch is considered a positive sign for a loose joint. Palpation has shown diagnostic use in human neonates, but is controversial and may have little diagnostic or prognostic utility in the dog. A caution: In human infants, it has been suggested that repetitive Barlow tests, and presumably Ortolani and Bardens as well, are capable of making infant hips unstable, thus giving a false-positive result. 17"
