It only solves the exploit path, not the vulnerability.

The true issue is that their hashing algorithm sucks. Any patch that doesn't fix the hashing algorithm is a band-aid and not a true fix.

It is somewhat risky to fundamentally change the hashing algorithm late in the release cycle (RC4). It is bound to cause problems. The ini-Option prevents the obvious threat without doing deep changes to the core.
