That's the first I've heard of any drawbacks to the 5065.  Can you give
more details on this?

The "as delivered" implies that there may be improvements available? Any
details on improvements?

I'm aware of Corby's optical filter trick, which improves SNR and hence
ADEV, but that would not affect sensitivity to temperature or pressure.
