Besides 'mame -cc' creating a mame.ini file if one is not present, it also adds/restores lines (options) missing for the respective version being utilized, from a mame.ini file that is already present.
Obsolete options/lines remain though.
Is there a different switch that already handles deletion of what is not utilized under mame.ini, or is it perhaps something that can be explored for incorporation into future versions of MAME?
