It will stop those who can figure out how????  It's a file in the
unencrypted portion of the image.  "extracting" would entail "geli
attach -j /pathto/foo.pass -k /pathto/foo.key /dev/foo0"

There is no effort involved.  And they are not "bypassing the
encryption" or "making offline access non-trivial".  They are "doing
it wrong".

I'm not sure that anything you said makes sense.
