We do this everytime for OVS in do_start_ovsdb of utilities/ovs-ctl.in with:
ovs_vsctl -- init -- set Open_vSwitch . db-version="$schemaver"

Is there a subtlety here?

It does initialize when a command is run. But no-one runs ovn-sbctl
commands right (unless for debugging)?. So any ovn-nbctl command that is
run with --wait=sb will hang.
