Using RequestContext means that all the context processors are run. This overhead isn't needed in all cases. So Django provides a way to render a temlpate without the context processors being run (if you use Context()) and with the context processors being run (if you use RequestContext()). If we always did the second thing, there would be no way to do the first thing. It's trivial (not just easy, completely trivial) to write your own version of render_to_response() if you always want to use RequestContext. The entire function is two lines long. Of course, you'll have to pass it the 'request' instance every time, so that it's initialised correctly, but that's the cost of wanting request-related stuff. Yes, we could have the default being the reverse of what it is now, but the arguments each way are pretty easily balanced. Sometimes you always want to use RequestContext, sometimes you don't need it at all. So there's no strong reason to change things when it's so easy to write your won alternative shortcut.
