Well. I for one would like to see that change. We plan to bring over employees from another venture to staff administrative functions in the next 6 weeks. If we use this, they will all know things they do not need to know about, including how we integrated it.
Besides, it was sold as non-branded. Anyone can go to /admin and read the copyright.
Will it break if we use .htaccess protection? This will at least hide the information from clients and resellers.
I think it should be removed like NOW. It makes no sense to me at all.
