The existing resolve methods are not to spec and we are working to replace them with new ones based on the `simplify_a_calculation_tree` method. These are marked as deprecated rather than replaced outright as work will need to be done on the caller side to be made compatible with the new methods, for instance the new methods can fail to resolve (e.g. if we are missing required context), where the existing methods will always resolve (albeit sometimes with an incorrect value). No functionality changes.
