That's because you've largely missed the point of the Gitlab product.
Register everyone with commit rights to EMBA.  And then hope they're
conscientious enough to kick off a test run before making a nontrivial
change.  This last step would be less of an issue if management ceased
clinging to a neolithic changeset procedure that keeps the dev base
artificially small and old.
