I think that's more or less the author's point as well. Modularity has some overlap w/ security (in the sense that we need stronger forms of modularity to get stronger forms of privilege isolation), but many of the other benefits of modularity that are usually the justification for adopting micro-services can be achieved through forms of modularity that assume trust (i.e. libraries, and other means of code splitting that may be bundled into a single unit of deployment).
