Yeah, I was wondering about that. Currently, we try to add feature bits to /proc/cpuinfo only when the kernel has done any enablement for them. For other needs, people should use tools/arch/x86/kcpuid/
If we say that adding those bits so that guests can export them doesn't count as a real enablement, then sure we can hide them initially.
I wanna say yes here...
