One thing I've found to be a big step to using the modelling products is the user experience. Guitarists want to make music not fiddle with menus and software. A physical amp has all the options visible and they are simple. One knob per feature is much more intuitive and faster to learn and use than one that changes it's behaviour per patch etc. So what is described as conservative could just be a shortcoming of modern products' interface.
