Not exactly .. and don't know how this compares to Tarski .. by installing Thematic and a child theme the left or right sidebar or both would display the hard coded content .. that's still as usual ..
the basic idea for my changes was to use either widgets or functions for the sidebar areas or asides .. if you define widgets and no actions, the defined widgets will be displayed .. as soon as you define actions, only the actions would be displayed.
Benefits are: writing actions is easier compared to widgets, a child theme could completely control the content and the position of the actions ('widgets') within the functions.php without the need to walk through the wp_admin menu. A child theme could even control the position of the actions depending on index, pages, archives, single page and so on without the need of additional plugins.
Removing a sidebar is implemented for the right / left / both sidebars .. and for these it makes sense. I might implement a similar function for the asides, just in case that someone wants to remove these asides from special pages or single posts.
