We have not implemented coarsening of Cofunctions. Coarsening the original residual is not really required for a linear problem, although firedrake would mostly treat any problem as if it were nonlinear.

I have just implemented it. The PR will be there soon, I just need to add a test.

The restriction operator definitely moves cofunctions to the coarse grid (but operates with functions because when we wrote it cofunctions didn't exist)

The code that is currently missing has to do with the symbolic coarsening of the residual one-form when we coarsen a NLVP.

I have made a PR (#3181) where I indeed use restrict.
