There is no problem getting the keys without any exploit in any new firmware... except one critical part: the PRIVATE KEYS. Before Sony corrected their flawed method of using unrandomized session variables, we could calculate it using two samples encrypted with the same private key MATHEMATICALLY. As of version 3.56, Sony has started properly randomizing this variable, meaning the only way the private keys will be retrieved is by sending in the Impossible Mission Force to penetrate Sony HQ and steal them from the protected computer they are sitting on.

As an exploit, it might not last through the next version of firmware, now that Sony is aware of the problem. Weak exploits are better off revealed right away (and you can be sure there are other exploits still to be discovered or already known by some parties), particularly in this case, where Sony has been made aware of it.
Another factor is that Sony has made a huge effort to baseline 3.56 - meaning all new consoles, all refurbs, and all factory repairs are updated to it. If the exploit is turned into a handy way to downgrade all those systems to 3.55 CFW, for example, how is that a bad thing? The right package can probably get 3.56 Service Mode "bricks" unbricked, and bring thousands of more consoles under the control of their owners, not Sony. That's a good thing.
