584461380,MDU6SXNzdWU1ODQ0NjEzODA=,3868,What should pad do about IndexVariables?,2448579,open,0,,,6,2020-03-19T14:40:21Z,2022-02-22T16:02:21Z,,MEMBER,,,,"Currently `pad` adds NaNs for coordinate labels, which results in substantially reduced functionality.

We need to think about
1. Int, Float, Datetime64, CFTime indexes: linearly extrapolate? Should we care whether the index is sorted or not? (I think not)
2. MultiIndexes: ??
3. CategoricalIndexes: ??
4. Unindexed dimensions

EDIT: Added unindexed dimensions
