Just use a relay like you should.

When is the last time you worried about the +30K ignition coil backfeeding
into the B+?

I've seen enough power supplies short back to the input via regulating
components, feedback loops, and even shorted windings to know that what I
stated is quite possible. Knowing this, I cannot consciously give advice to
anyone to  preclude their own safety.
