In any case a new arm_features bit is hardly a big deal: the actual question is whether it makes sense to provide this register that shouldn't really exist for the cpu configurations we're modelling.
I use Qemu to run unit tests for a real-time operating system that runs on real Xilinx Zynq or Altera Cyclone-V for example. Both systems use an ARM Cortex-A9MPCore with Security Extensions. The operating system will run in secure mode all the time within a single address space and one-to-one mapped addresses. Everything we use from this Security Extensions is the VBAR. So for me the only missing Qemu feature is the VBAR if I want to use nearly the same binary on Qemu and the real hardware.
