Hi Timur.

Done. This is applied in the latest v8-0002.

FYI, there was some reason for requiring both parameters to be set,
related to issues when using vci in single-user mode. However, being
such a niche problem, it was judged better to remove such code
complications from the current patch 0002; we can revisit this in
future if necessary.
