Description
There are several places in [smartptr] where we require that T(*)[] is convertible to U(*)[] for some types T and U. The mdspan proposal adds another.
It might be helpful to have an exposition only helper for this.

Research direction
Read the existing requirements in [smartptr] that use convertibility of T()[] to U()[], then compare them with the related need in the mdspan proposal P0009. Determine whether a shared exposition-only helper should be introduced and where it would apply; done means the standard wording has a consistent, agreed treatment.
