Sure will remove the fix tag, it was added as per previous feedback.

Currently atomic-check() path we do feature's requirement/dependency check and then compute-config which will be applied in atomic-commit.
So I also feel _check() or _compute_config() suffix will be good for all functions in atomic-check() path.
Regarding passing argument to any function, I see it is used as per need.
