A valid point! The one we're using are about 1/2 the size of a dime.
Unfortunately I'd think standoffs (or any other method of raising
the body above the board) would create the  longer moment
arm leading to shake table failures as well, for the more
massive MOVs.
Good point!

Harris' suppression division is now Intersil.  Preforming MOV leads will
cause failures if the device is subject to vibrational tests like those
required by UL for consumer devices.  The preform weakens the lead and it
eventually fails due to the vibration.  However this is only what I have
found in the past and only on huge devices, not those tiny ones that are no
bigger that a dime.  I am talking strictly about those 150V 80 Joule and
above type of device.
