Why so aggressive?
Some people around here use it to build embedded software or virtual machines.

While HotSpot is not a good example, it does not use C++ exceptions either.

Not that our stuff is high performant, but we just don't need exceptions.
The VM code is 'stable', exceptions are handled on that language level.

And if I look at LuaJIT2, I would say, it is also not worth the headaches to support C++ exceptions in a VM.

So, I would prefer if -fno-exceptions and -fno-rtti remain at least an option.
