I think this will become possible soon, but not yet. The sagemath doctests are adding "feature flags" which detect features in the environment, but this is not yet completely polished for cython / external libraries / fortran code.

At this time, I'd rather focus on getting sagemath working on cython 3 so we can update cython (see #45086 and https://github.com/ahesford/void-packages/pull/2). After 10.2 or 10.3 it may be easier to do this.

In any case, I'd like to see a detail of how much is saved (say how much download/disk it takes now an install of sagemath with all deps not standard in void vs. what would it take if we get this "savings"). If the savings is not really very significant, I'm not sure I see the point...
