Excellent! I have a few subclasses of ConfigParser that do these things,
too. Glad to see it in the standard distro :-)

API changes probably ought to be discussed on this list (which includes the
maintainers of any code). Basic point: the "maintainer(s)" is usually quite
unclear since we avoid attribution within the source if at all possible.
Posing the suggested change here allows for changing maintainers (note that
Fred has done a tone of work on ConfigParser, and I've submitted a few
changes myself, too!), and it allows for broader input.
However, bug fixes and minor reworking should probably be allowed regardless
of the maintainer. I'd hate to end up at a point where the Python
interpreter is partitioned into a bunch of little fiefdoms, where you must
pay a toll to enter.

The string.lower() at lookup time shifts the performance response, but I
don't really see config state as performance-intensive.
