Indeed, as soon as one vulnerability is plugged another is exposed. 
However Adobe are inching forward with extra layers of security, such as 
black-listing of individual JavaScript functions, see 
http://kb2.adobe.com/cps/504/cpsid_50431.html, and so for most users it 
does make sense to swim with the security-flow. Although as Dumas 
once observed -- all generalistions are dangerous, including this one.
Hence it is easy to pick holes in such statements.
