I think it extends beyond "do development of software in a lean way", and should also include "make more things configurable with software/firmware instead of hardcoded in hardware". In the starlink case, I imagine they could somehow reconfigure the SDR on the device to get around jamming. If instead the entire chain were done in hardware, then making these kinds of changes would be rather difficult. At the same time, if more things are software more things become targets, so you need to care much more about the actual security of these kinds of update systems.
