No its not silly. Someone who is new to DSLR's would very much start with using it in auto mode and slowly move on to setting changes as they learnt and picked up on how to use the camera.
Flashing firmware etc is for more advanced users who want further control of camera settings.
Pearl is new to DSLR's and is not technical. She needs to start with the basics - using auto mode for now while slowly learning her way around the camera. If she feels limited after that, then flashing the firmware is the next step.
What
is silly, (in my personal opinion) is telling her to flash the firmware with MagicLantern and start using it straight away when she is a complete beginner to DSLR's in the first instance.
Just my opinion of course
