I think they got it from the OpDSL code generator where it was done because the DSL was defined in terms of the printed form of affine expressions. So it included a parse as a shortcut to the DSL needing to reify the build logic. That is tedious to do generally but not hard to do for any specific case: just use a normal API for constructing this specific affine map and don't use the parser.
