We did use distutils.util.strtobool(os.getenv(key, default)) for a while,
eventually we just built a helper that did the same because it's easier /
more comfortable.

Can you elaborate? Here's more or less what I had in mind (using the
os.getenv source code as template):
from distutils.util import strtobool
def getenv(key, default=None, to_bool=False):
"""Get an environment variable, return None if it doesn't exist.
The optional second argument can specify an alternate default.
key, default and the result are str."""
val = environ.get(key, default)
return val if not to_bool else strtobool(val)
Sure, there are other ways to implement that are probably equally trivial,
but why does that matter?
