We are able to express 3 levels of runtime dependencies in Debian - Depends, Recommends and Suggests. There are no hard rules on what goes where but there is a general convention that Depends is for vital things, Recommends is for "standard" user-level things, and Suggests are totally optional. I would suggest for sagemath:

1. Depends is for all mathematical functionality.
2. Recommends is for extra user-oriented stuff like commands to pretty-print docs.
3. Suggests could be for power-user or dev-oriented stuff like additional tools needed to run `sage -t`.

All of these would need to be added to the "Build-Depends" for the sagemath source package since we run the tests during the build.

However if cython/sphinx aren't needed for (1) or (2) then we can avoid having the sagemath binary package depend on them, saving users some disk space.
