The point, at that point, is to show the selected
candidates in the context of all candidates.

See my reply to your mail about that.

Retrieving a value from a history list is more
tedious than choosing a saved-candidates-set
variable from the set of such variables, using
completion.

That would be especially trie if your history
list contained also other stuff (e.g. values
returned from the minibuffer, as for normal
minibuffer histories).
