Are you seriously saying that by the time you've got a cross toolchain,
target libraries and target os running testsuites on a simulator that
the complexity of pressing the self-hosting button for a compiler written
in C++ would be harder than fixing a few bugs that you'd have to fix
*anyway*? Heck, at that point you've got a cross toolchain that should
produce the exact same binaries as your self-hosted compiler -- that's
a simple way of detecting if there's a bug in your self-hosted system.
