Looking at them, I noticed they were all defined as "default y". The issue is that the test simple removes the config and re-runs make oldconfig, which enables it again because it is set to default 'y'. Instead, explicitly disable the config with writing "# CONFIG_FOO is not set" to the file to keep it from being set again. With this change, one of my box's minconfigs went from 768 configs set, down to 521 configs set.
