[nitpick] The two
TrialFESpaceoverloads at lines 417-422 and 424-429 have identical implementations. The second overload (whereDistributedCellFieldis the first argument) simply calls the same underlying GridapTrialFESpace(s,field)function. Consider consolidating these into a single implementation or adding a comment explaining why both argument orders are necessary.
