Perhaps.  How many people are talented enough to understand the 
vulnerability and how it's exploited and know *for certain* that they 
won't have a problem?

It would be different if we were talking about an app that isn't exploited 
much.  Php is exploited every day, even when it's fully patched, due to 
the complexity of the attacks and the lack of understanding of most people 
who code in php.
