In the same vein, you can look at assistant.el (part of Emacs and Gnus).
It tries to address exactly this need without any library dependencies
like EIEIO's Custom Mode. It uses the Customize widgets. It lacks
documentation and practical use cases, and hasn't been updated in a
while though.  So it really needs a maintainer IMHO.
