I do hear this kill a lineman a lot as soon as any talk goes into backup power.
How many linemen are killed a year in the US due to backup generators or similar? Are there no procedures they can do to work on lines safer?

But since lives are at stake here, we prefer to have layers of protection rather than just one thing. Grounding jumpers can fail if not properly connected (a large mechanical force will be applied to the jumper when the phase-to-ground fault current flows through it).
Bottom line, respect the electrical code and connect generators through a transfer switch. These rules are in place for a reason.
In fact it's likely the transformer on the street between your house and the network that's responsible for the death of the linemen. IIRC that's a step down transformer (so step up when run backwards like this.)
