Regarding "instantaneous thrust" due to free wheeling of the core enigne:

With advances in computer logic, it is possible to do the same thing on a
tubofan engine as well. There are turbofans in production that do just
that. They use the variable geometry vanes in the high compressor to "free
wheel" the core during throttle decel transients. This allows a quicker
re-accel and a quicker re-establishment of take-off thrust.
