De link :
-hide_banner
is the bane of those providing help. Making it the default would make providing support more difficult and less efficient. It hides important and useful information.We require the user provide the full command and the complete console output when they ask for help or submit a bug report. Quite often we have to request this information resulting in an unnecessary delay. Making this the default could result in yet another step, more information requests, and more delays. We would have to explicitly mention
-show_banner
for every single help request and bug report. Making-hide_banner
the default would result in more work for users and developers, frustrated users, and fewer questions answered.
