That only places a very limited modification to see a subset of the data or audit actions. If the secret reasons the OP can't talk about aren't that, it's not applicable. Also see Pete Finnegan's VPD security pdf and various other row level security docs on the net, as well as special code needed for things like weblogic and bugs with some tools. http://download.oracle.com/docs/cd/B19306_01/network.102/b14266/apdvpoli.htm#CHDECFBF for how it applies to different access models. There's other things like sys being exempt, you need to make others exempt to get a complete export, parsing and optimizer issues can occur (sometimes things may go faster if the data is limited properly - but additional administration is necessary regardless), and a lot of other more obscure issues may need to be addressed.
