I'm sure the material, the remaining fastener as well as the position and spacing of the fastener holes would enable any expert to uniquely identify the aircraft model with no ambiguity. Similarly any marine biologist should be able to confirm or deny whether the piece spent a significant time in seawater or not.
Unfortunately even if it does get confirmed that it is a T7 part, and by inference almost 100% certain that it is from MH370, it gives almost no further information compared to what we already knew from the flaperon (except corroborating that evidence).
