I think the requests are starting to be a bit unreasonable. Tao is replacing a reimplementation of a standard function with that standard function / compiler builtin. We don't put such a high burden on that. And once the proper existing fields are used where possible as shown in my reply just replacing the rest seems totally obvious - quite contrary I think keeping a reimplementation would need a high bar.
