I think it very well could be Joomla and Wordpress. Many hosting companies for example offer a one click install of WP. Some designers specialise in this.
I appreciate what you are saying here and if it is any consolation I am in the same boat. I have even started offering some clients free updates rather than have then hacking around what I have created for them.
