TSG and the Default Web Site

During the installation process the TSG services configure the IIS services to listen on port 443 of the Default Web Site. So in addition to listening for RDP over HTTP(s) connection attempts the TSG server is also listening for regular HTTPS traffic. To see this behavior you simply need to open up your browser and point it to your TSG server. You will see the default web page that is configured for the Default Web Site. Is this a bad thing?
