Maybe we are perceiving different issues.

The issue i am talking about is that Registrars (Cloud or Owner) and MASA may be
installed in cloud environment where the SNI "server_name" extension in the 
ClientHello
is necessary for the Registrar/MASA to be addressed. This happens when multiple
virtual servers, with different domain names and for each domain name 
potentially
a different certificate share a single IP address. The SNI is then used by the 
cloud
infrastructure to demux the incoming ClientHello to the right application.
