The main benefit is that you use a standard file format that gives you a
data structure, e.g. a dictionary of lists.

To use a simple text format, we need to design it well. For example, keeping
multiple dictionaries of lists in one file might be annoying to parse in
shell. On the other hand, you don't want to create one file per variable,
because this can kill performance (start up times). Having a command line
utility has the advantage that you can change the underlying mechanics
without changing the API. If you use text files, it is harder to change that
because you might have 15 different parsers already scattered throughout the
code (and the world), with different bugs and quirks.

Simple text files might still be better; I just wanted to point out that
there are concrete benefits of using a standard file format.
