I have certainly reached for them in other circumstances, to scope a
'helper function' as local to the code that needs it.  Maybe it's my
Pascal background showing through, although I have not actively written
pascal for close to a decade now.

Usually when I reach for local functions it is purely a scoping
mechanism, and I have no interest in accessing local state of the
enclosing function.  Accessing that state is what seems to bring the
complication, but also all the interesting use cases!
