Isn't it more or less a case of usually launching an application into a newly created window? It's been a long time. The Plan 9 emphasis on per-process namespaces corresponds to the idea that a new graphical application is given a handle for a framebuffer that corresponds to the size of the window it can draw in. The Rio idiom has every window start by default as a textual terminal, so it's natural to be able to take over that framebuffer to run a graphical app. It's a bit like the situation on older systems, like Sun workstations, where the textual console and the graphical display were only informally separated: sometimes the X server's display would be interrupted by lines of text printed onto the screen by the kernel's console driver.
