Although you're right about electronics withstanding the accelerations
of the slinger, rocket motors are not usually so sturdy. It may take
some development to make them work and survive. Hypergolic rockets have
been used in air-to-air weapons and they could withstand 50g axially.
But hypergolics are not as efficient and pose handling risks.

the orbit. A hyperbolic escape trajectory is, of course, possible
without using a rocket engine./
The article does say "a booster affixed to the payload will then give
it an extra push to guide it into its orbit". If you gave the payload
a small kick when it's at its high point in its orbit you could raise
its low point enough to avoid the atmosphere. And if you could just
give it enough of a headstart that a one or two stage rocket could do
the work of a three stage rocket that would be a huge advantage
