"this type of functionality should have been handled via a plugin or theme CSS"
To begin with, a statement like the above is completely WRONG! Why you don't handle bold and italics in texts with plugins or theme CSS? It's the same logic here.
First of, you CAN'T handle individual image borders with theme CSS. It's obvious you never used such option to make that sort of statement. Secondly, it's more than stupid to remove core functions that were working just fine and move them to plugins - while, at the same time, you add features at core that should have been at plugin territory, such as media playlist management!
