Same as it's been for a LONG time and never failed an inspection. Thousands of cars that pass NHRA tech every weekend use a ford solenoid in the trunk wired just like that schematic.
If you want the starter draw going through the master, then have at it. Some of us don't like a big honking wire when the master is on going forward.
Reality is, if the master kills the engine and fuel pump, they pass you.
Until a tech inspector or NHRA says it's not OK to wire that way, it's staying. My starter may run away if the ford solenoid gets stuck closed. When it happens it will be a first for myself and anyone that I know. My way may not make you happy or your interpretation of the rule, and that's OK.
