One potential issue is that the migration instructions for v1.5.0 ask developers to specifically create the ServiceAccount manifest [1]. When make bundle is run, it generates the serviceaccount YAML for the bundle, and many projects check this file into version control.

It seems that the bundle's SA manifest be removed when upgrading to v1.13.1?
