Why don't you ask Madza? I'm sure various locations were researched by a bunch of their enginners before that one was decided on.
The problem with the stock location is that very few aftermarket senders fit, and you should not use adaptors because they space the sensor out of the coolant flow. The next best location is a drilled and tapped hole in the water pump under the thermostat.
The radiator hose is a bad location, as a stuck-closed thermostat will cause a cold temp reading even as the engine boils...
