I'm wondering how many here are really looking for the sound that many of us have become used to when playing through a real amp, that is actually not the design intent of a device like the Axe Fx is, assuming I understand the design intent, which if I do, is to have a unit capable of reproducing the sound of many different amps, close-mic'd,* in a quiet studio with no extra sound coming from the reflections, due to those extra reflections being unwanted to get a clear mix, and then adding them in in either post production or @ FOH, depending on the sound you desire on your recording, or what the venue/room your playing live in, requires for the band to sound good.
* From the manual/blocks guide: As guitarists, we are accustomed to the sound of a speaker “in the room,” but this is not what our audiences hear. For recording and performing, the close mic’d sound is essentially a universal standard. THIS is the sound that the Cab block is designed to reproduce, and this explains why not only guitarists, but recording and front-of-house engineers have embraced its use.
Of course, rules can be broken, especially to achieve new sounds and bolster the creative process. But in the context of AITR, are we looking for this sound simply to enjoy the "alone" playing experience, but it's not really the best use in the recording or live sound environment? Perhaps it's analogous to many of us creating that killer, scooped tone, that sounds amazing by itself, but in a band mix, fails to cut through, or to guitarists wanting to use their amp on stage, yet it fighting the FOH mix...?
Whatever the reasons for the desire by many here to alter the way the AF3 works in order to implement this feature, I'm quite interested to see how the next FW will handle the issue of the lack of NV memory in the MkI.
