1. Only check the `.data` of non-index variables, done at https://github.com/pydata/xarray/pull/5906/files#diff-763e3002fd954d544b05858d8d138b828b66b6a2a0ae3cd58d2040a652f14638R4161-R4163
2. The check for whether or not a full index was needed is done in a `for dim in dims` loop, but the condition doesn't actually depend on `dim`. So I lifted that check out of the for loop (doesn't matter much, since stuff is cached).
