What's a winodw ? :-)

"It no longer has a use" suggests it does nothing so might be better 
phrased as
"no longer the recommended or sole way to perform this check and is 
superseded by .. "


Is there a CCC for this ? It seems that there's a compatibility impact
on permissions required if you don't/can't change your code, and on your
code if you want to keep the same permissions.
