Review Comment:
[arrow::dataset::internal::Initialize](
https://github.com/apache/arrow/blob/a1707dba7c9ec4265c048586c485c526048cf162/cpp/src/arrow/dataset/plan.h#L29)
could certainly call `arrow::compute::Initialize`. However that function only
registers dataset ExecNode factories, and isn't used here. Implicit
initialization is something I'd recommend avoiding until we can provide better
guarantees
