I was wondering whether config-store could be leveraged to save the initial
state of defaults and reload it every new test.

Isn't this in general an issue of running multiple simulations from one main();
i.e. the same problem would be exhibited in programs like this one:
examples/wireless/wifi-adhoc.cc ?

Should we be advising people not to do this and to do multiple runs from
outside of ns-3 main programs?
