Seriously?  You went from a numpy-friendly feature to something rather
numpy-hostile.
In numpy, ndarray.size is an attribute that returns the number of elements
in the array.

The constructor that creates an arbitrary repeated value also exists and is
called numpy.full().

Even ignoring numpy, bytes.size(count, value=b'\x00') is completely
unintuitive.  If I see bytes.size(42) in someone's code, I will think:
"something like int.bit_length(), but in bytes."
