If it boils down to that choice, by default I would pick security over

It was a bit of a maintenance nightmare (the file was maintained in
every distribution rather than centrally in openstack). Another issue
was that we shipped the same sudoers for every combination of nodes,
allowing for example nova-api to run stuff as root it should never be
allowed to run. See  for the limitations of using sudo which
triggered another solution in the first place.
