I’ve split this thread as it’s unrelated to the question that was asked in [DataFrame: Cannot have duplicated names for indices](https://discourse.julialang.org/t/dataframe-cannot-have-duplicated-names-for-indices/78396). I understand that InMemoryDatasets uses a different philosophy than DataFrames here — and that’s great — but let’s please not make usage questions about either of these packages a battleground on their respective design philosophies.
