Honestly, it annoys me.  I often temporarily delete the TDX MAINTAINERS entry when
sending patches that affect arch/x86/kvm/vmx/tdx.c, because many, if not most, of
the KVM changes are purely mechanical and/or KVM-internal that don't have much to
do with TDX as a whole.  Although maybe that's just a reflection of the types of
patches I tend to send.

But I do that purely to try and not pollute x86@ and linux-coco@ with stuff I'm
99.9% certain they don't care about.  If y'all want to sign up for spam, I won't
stop you. :-D
