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.
Yes, a good point. Like using alcohol fuels with peroxide, using methane
with LOX loses you some fault tolerance, which can make life undesirably
exciting when things go wrong. It's a feature, not a bug, if your fuel
and oxidizer can't quietly mix and form a liquid explosive.
