Gabel/Derek,
AS we have done on many projects a butt hinge welded shut after erection seems to satisfy any design anti-lift or movement factors. If not set up from the floor level on piers then some bitchithane between the upper half of the hinge and the post bottom defeats moisture wicking. If the hinges are set in the concrete and lagged to the post bottom they can be used in raising the bent. Kinda requires some very careful measuring and placement efforts. But isn't that what the TF is famous for ?
