In many examples where I used structured dtypes a long time ago,
switched between consistent views as either a standard array of subsets
or as .structured dtypes.
For this usecase it wouldn't mat

happening, especially in working with large arrays. They really should
be used everywhere it is possible. In this respect, I think one has to
weigh breakage of
