Its nothing to do with their mindset, its to do with knowing EXACTLY what the
code is going to do and/or where the program counter is going to go. There
is nothing to fall back on to tidy up any fuckups and no C++ runtime to hold
your hand.

You could in theory do a lot of things. Whether the time and effort and extra
bloat would be worth it is another matter. Also the STL throws exceptions and
does hidden conversions.

Oh yes they would. The kernel already has its own type of exceptions and has
to deal with low level interrupts. The last thing the code needs is C++
exceptions where something gets thrown and the program counter ends up god
knows where because someone forgot to do a catch 5 levels up.
