Comment(by josefpktd):

 broadcasting is not a strict requirement. If I remember correctly, only
 vectorized evaluation (1d with x and shape parameters of the same length
 or scalar shape parameters) is required for the current private methods,
 (_pdf, _cdf).

 So the broadcasting test could be disabled for some distributions (and
 replaced with a weaker version).

 (I think, there are no systematic broadcasting tests for private methods
 in the current test suite, but some public methods break if it doesn't
 work.)
