Does anyone have any comments on the viability of a spacecraft such as the one I posted in the link below?

(I couldn't figure out how to post a photo so I posted it to my Facebook feed and linked it below.)

I'm sure more learned people have considered such an intermediate approach to provide artificial gravity while conserving construction costs but it's hard to find information about current research on it.

If a successor to the ISS has been in the planning, why can't it be a partial torus?
