Wes McKinney commented on ARROW-7071:
-------------------------------------
It'd be best to not mutate any existing arrays, but instead to do something like
{code}
masked_arr = arr.with_validity_bitmap(bits)
{code}
I'm a bit ambivalent on expanding the usage of {{pyarrow.array}} but that might
not be too bad either. These need not be mutually exclusive
> [Python] Add Array convenience method to create "masked" view with different
> validity bitmap
