They keys are checked now, so I think this is resolved.  (Tested on windows and Mac).

>>> os.environ[''] = 'X'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/iritkatriel/src/cpython/Lib/os.py", line 684, in __setitem__
    putenv(key, value)
    ^^^^^^^^^^^^^^^^^^
OSError: [Errno 22] Invalid argument

>>> os.environ['a=b'] = 'c'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/iritkatriel/src/cpython/Lib/os.py", line 684, in __setitem__
    putenv(key, value)
    ^^^^^^^^^^^^^^^^^^
ValueError: illegal environment variable name
