Nobody should rewrite rails and activesupport and the entire ecosystem using refinements. It would be a massively breaking change for little purpose because activesupport is so well known to the core ruby team. Nobody who is greenfielding code should copy the activesupport pattern, though, and you aren't losing anything by being told not do that, you're being shown a better way.
