It's not that I don't think it's important.  I think the *bugs* are 
important to fix, but that the root cause just *cannot* be fixed.  It's 
just that:

1) the many people who made the same mistake maybe were just 
cutting'n'pasting buggy code;

2) especially, the fix is not 100% safe unless I'm mistaken.
