[Numpy-discussion] hashing dtypes, new variation, old theme

Running the test suite for one of our libraries, there seems to have
been a recent breakage of the behavior of dtype hashing.
import numpy as np
data0 = np.arange(10)
data1 = data0 - 10
dt0 = data0.dtype
dt1 = data1.dtype
assert dt0 == dt1 # always passes
assert hash(dt0) == hash(dt1) # fails on latest
fails on the current latest-ish - aada93306 and passes on a stock 1.5.0.
Is this expected?
