Ability to restrict connections by client version

It would be great to have an option in the dashboard to restrict connections to the network by client version. For example, we could restrict to “latest version -1” meaning 1.6.6 or 1.6.5 is allowed to connect. Or we could restrict to minimum version (key in the number “1.6.5”), but this doesn’t fill me with as much joy as it then becomes a manual job to change said version.

Further, if it could then automatically update the client and re-allow access, that would be great too.
