Yep. If you see Emacs as a text editor with lots of features, then it's doing lots of things. But, if you see Emacs as a platform that comes bundled with some apps by default, then its "one thing" is to be a text-oriented app platform.
The whole "do one thing" slogan is kind of vacuous anyway; e.g., what if my "one thing" is "implement all WWW standards to be able to use any web page"? Is that still "one thing"? If not, then wouldn't implementing only "one" part of WWW be useless?
