It's appealing, but not really a good option. For example, over the years
we've had many users confused with GNU Mailman's configuration file, which for
versions < 3 was a Python file. People would put quotes in unnecessary places
(e.g. turning an int into a string), or forget one of the three closing triple
quotes for multi-line options, etc. There's really no reason to expect a
system administrator to be a Python or Perl programmer in order to configure
your system.
For Mailman 3 we switched to an ini file, and while that version is still in
beta and hasn't gotten nearly the same real-world exposure yet, I'm convinced
that it will be easier for end-users to manipulate than either Python or XML
syntax.
