I don't have a strong opinion about the device_span. Since it's not a detail API, I think technically it should be exposed in pylibcudf

[vyasr]

I don't expect pylibcudf users to ever need the equivalent of a device_span. In C++ spans are useful as a way to create views on data owned by another object, but in pylibcudf Columns already have this ability baked in because they have to match Python's referencing semantics. The pylibcudf implementation in this PR demonstrates that since they only take Columns (you didn't bother to create a span overload). With that in mind, I don't think it's important to expose span-based libcudf APIs to pylibcudf if there is a column-based alternative.
