Anthony Williams's paper on parallel algorithm complexity, p0574r0, includes wording that would resolve LWG issue 2919, and I suggest we defer initial triage to handling that paper.
The specification for adjacent_difference has baked-in sequential semantics, in order to support reading/writing through input/output iterators. There should a second specification more amenable to parallelization for the overloads taking an execution policy.
Proposed change: Provide a specification for the overloads taking an execution policy this is more clearly suitable for parallel execution. (i.e., one that does not refer to an accumulated state.)
