Take a close look at the photos of Malones nice little voltage reference boards (http://www.voltagestandard.com/Home_Page_JO2U.html).   The voltage reference chip is mounted on an isolated peninsula of PC board material to help isolate it from stress due to environmental changes.
If the humidity effect is strictly from mechanical stress on the die as the plastic encapsulant swells or shrinks, would a part in a metal can then be immune from this effect, even if it was non-hermetic?
