This one here is really interesting.  It also states that low voltage
isn't much of an issue but what's really interesting is it's almost a
word for word reprint of a document from the Nichicon datasheet.

Page 101 of this next document says the same thing as my reference.  

"The effects to the life by derating of the applied voltage
etc. are neglected because they are small compared
to that by the temperature."

Essentially they ignore it.  They certainly don't say watch out for 400V
caps used at 3V.

There's a lot of hearsay in the archives with no evidence to back it up.
Only theological arguments that just because you can't see it doesn't
mean it doesn't exist.
