With 'ignore' a warning is still raised--is this by choice?

>>> import numpy as np
>>> x = np.array([0, 1, 2.])
>>> with np.errstate(divide='ignore'):
...     x/x
__main__:2: RuntimeWarning: invalid value encountered in true_divide
array([ nan,   1.,   1.])

(I see it is documented that way as well, so I suspect so.)
