That's what "RESTORE" part of CONFIG_CHECKPOINT_RESTORE refers to: the ability to restore (reconstruct) a process.
If you want to be able to restore a process, you need RESTORE feature. It's that simple.
Why do you want yet another config option for it? What's the problem if you simply enable CONFIG_CHECKPOINT_RESTORE?
The only problem I can imagine is "CONFIG_CHECKPOINT_RESTORE enables too many things I don't need".
Frankly, I find it not very likely, unless you are planning on working on resource-constrained machines (like mobile phone).
