Re-parsing this, I think there was a mis-communication :

I'm not at all suggesting that the doc should _not_ say that data will
be corrupted.
I'm suggesting that in addition to what it currently says, it also
should say that the on-disk data won't be
changed by the page zeroing mode.

In my searching I found countless people over the past few years who had
been similarly confused into believing that it would write back the
zeroed page
to disk.
