This is splitting off some "usefully anyway" test changes from #51082
We have several places internally where we mutate the
df.values[..] = ..directly, while this is certainly a discouraged pattern (also only work if you have a single block), and often easily avoided by usingdf.iloc[..] = ..or mutating the array before creating the DataFrame, instead.
