IMO any key that isn't bound should fallback to its standard binding,
and the keys should only apply when the focus is in the minibuffer, like
other prompts (e.g., find-file).

In terms of implementation, I think this would mean binding the map only
in the minibuffer instead of using read-key-sequence.
