There's a lot of stuff. And the reason is that distributions usually build in support for a large amount of diverse hardware. These are modules (=m) where possible. The motivation for this is: when you have that heart rate monitor, intertial measurement unit, magnetometer or something else, you just plug it in, the module gets loaded and the device just works. Some things have to be =y and are unable to support =m. To tidy up the garage, build a custom kernel and be loose with the use of =n.
