Fair enough. I can certainty agree with the last bit. Perhaps I (or

Hybrids combine the complication of solids with most of the complication
of liquids: you have to rebuild the "hot section" of the motor to put in
more fuel for each firing, even though you have a feed system with tanks
and valves to deal with etc.
