Use-case:

Add an enum with say 200 levels; int8 is chosen as the underlying index type
Subsequent data write with 80 new levels; int16 is now necessary since the 8-bit boundary is crossed
This operation needs to function seamlessly, with solid testing and documentation as always

This is not a blocker for the 1.5.0 release but needs to be on the roadmap.
