Making a rocket engine as big as one of the five in a Saturn V that
will work safely will require a fair amount of research and testing,
so although you're probably right, the investment in all the static
tests to ensure the engine would not blow up on the launch pad is of
enough value that it is understandable that it would be desired to
make use of it if possible.
