It even makes a copy, right? I agree it will _typically_ not be the case, but it can still be the desirable behaviour for any context where you need a 1D array (and expect `to_numpy()` to give you that). Another example of such context is constructors like `pd.Series` that expect a 1D array. FWIW it does not make a copy. Similarly as our ListArray -> numpy convrsion, each subarray is a slice from one converted parent ndarray (of course it still needs to allocate the object-dtype 1D array that hold those zero-copy subarrays). -- This is an automated message from the Apache Git Service.
