But you lose some of that benefit with the extra precautions you have to
take against inadvertent mixing of fuel and oxidizer. Which is always
bad, but extraordinarily bad when they are miscible in a common liquid
temperature range.
Common bulkheads, for example, may not be possible without introducing a
mass detonation hazard that makes catastrophic failure of large solid
motors look benign.
