So imo traditional transistors and mosfets are quite fundamentally different.

I didn't say they weren't different. BJT, IGBT, and MOSFET all have a T in their name, because they are all still transistors. A transistor at it's basic definition is a device that amplifies and/or switches the flow of current. It doesn't state that the amplification or switching is based on current or voltage, either can be used.

You don't say a delta printer isn't a 3D printer just because it operates differently than the original cartesian printers. They are all still 3D printers, just like BJTs and MOSFETs are all still transistors. They just operate differently to ultimately fulfill the same end task.
