IMO the argument isn't that you have 5 generalists, but rather that you might have 1 FE engineer, 2 software engineers a DBA and a Devops engineer (or at least 5 Software engineers that are more or less 'specialists' in those domains) This allows you to have a self-contained micro-team that can approach each value-add opportunity from the perspective of the overall solution, without any of the bureaucracy of communicating with someone outside of the team.
