Only qemu-system-FOO and qemu-storage-daemon provide QMP
monitors, therefore such declarations and definitions are
irrelevant for user-mode emulation.

Restricting the x86-specific commands to machine-target.json
pulls less QAPI-generated code into user-mode.

Is this still true without "qapi: Restrict code generated for
user-mode"?

Markus, Eric: what's the difference between machine.json and
machine-target.json? commit 7f7b4e7abef4 ("qapi: Split
machine-target.json off target.json and misc.json") explains what
but not why.

Why the visit_type_X86CPUFeatureWordInfoList() stub was required
in v3, but not in this version?
