What math is saying is that we can patch all the loaders and things, and create a 3.56 firmware that has downgraded keys. That's fine... but you still can't flash THAT to a console that already has 3.56 OFW installed.
That said, the bigger, more important question is: WHY would we want to make a 3.56 CFW... and while there may be a resounding "YES" if we COULD update over OFW 3.56, the reality is that it's a big question mark since WE CANNOT flash over OFW 3.56.
Let's reiterate this in other terms: 3.56 has ZERO new features for applications. There are absolutely NO GAMES that might "require" 3.56 that cannot be made to work in 3.55 CFW.
I originally thought 3.56 would be a good thing, until I realized that once flashed to 3.56 OFW, a console is hosed. My misconception was that a CFW 4.56 would be able to flash on a 3.56 console... but that's not the case. The HMAC is no longer the sole key needed to build an acceptable package that can be flashed by 3.56 OFW.
So yes, 3.56 has become pointless. It is worthwhile to analyze the hell out of it, so we understand how to decrypt and customize future firmware versions. If a 3.60 firmware comes out that adds new, must-have features or real improvements in performance, it might be worthwhile to create... or it might be worthwhile to simply add the updated components to 3.55 CFW - but until that happens, 3.55 is king.
