Once they have approved, this approval is indefinite, and subsequent imports [of the same scope](https://gitlab.com/gitlab-org/gitlab/-/blob/ade620e1d1d613ce84a681acc310c207d8b5130e/lib/gitlab/import/source_user_mapper.rb#L38-41) (including root level destination namespace, import type, and source host name) will assign imported contributions to the user directly. ### Problem A user cannot stop subsequent imports (of the same scope) from assigning contributions to them. ### Proposal Allow a user to revoke their approval after it has been made.
