That is theoretical. Which platform will break or feel distressed if we make it unconditional. That is real world.

Yes. There is so little code behind CONFIG_CHECKPOINT_RESTART that it won't help with that.
But if minification is the actual requirement for disabling CONFIG_CHECKPOINT_RESTART than CONFIG_CHECKPIONT_RESTART is properly behind expert and it needs to be default y instead of default n.
