Why exception from os.path.exists()?

This surprising exception can even be a security issue:
>>> os.path.exists("\0")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib64/python3.6/genericpath.py", line 19, in exists
os.stat(path)
ValueError: embedded null byte
Most other analogous reasons *don't* generate an exception, nor is that
possibility mentioned in the specification:
https://docs.python.org/3/library/os.path.html?#os.path.exists
Is the behavior a bug? Shouldn't it be:
>>> os.path.exists("\0")
False
