But we are about to tighten the input visitor, at which point user_creatable_add_type() MUST follow the same paradigms as everyone else, of pushing into the struct before grabbing its keys, because the value of 'name' should be ignored on the top-level visit. The change has no impact to the testsuite now, but is required to avoid a failure in tests/test-netfilter once qmp-input is made stricter.
