There's nothing special about those schematics. It's simple preamp, cathodyne phase inverter, and vanilla power amp and power supply.
There are amp models in the Axe-Fx that are far more unique than that, Hook Captain for example.
The limiting factors are availability of schematics, availability of reference amps, time and consumer demand.
