The only reason I was thinking to temporarily keep struct wp, is to keep cli_classic compiling. So that _wp_ functions can be added one at a time, with implementation. At the end of the patch series there would be no struct wp, one way or the other.
I thought this can be another approach on how to add one function at a time.
