Comment from Mike Pajevski:

From a security perspective, you need to consider that a client must be able to require TLS to the server. You cannot depend on the settings on the server — because an attacker could somehow redirect a user to a bad server that does not use TLS. If the client will fall back to an open connection in that case, the client will be using a bad server.

Based on this, I will add a configuration parameter to require secure transport from the C Client:
