Depends on your viewpoint. To me, the terminal is a fixed sized canvas (as long as you're not resizing e.g. a window or something). The fact there's auto-scrolling and a backlog are features of your shell, less the terminal emulator itself (even though backlog is actually implemented by the emulator). This comes down more to philosophy than anything, though.
