Not a big fan of solving an organizational issue (how several people can work together on a same project) with a technical solution that adds more complexity and has its own drawbacks (splitting a project into micro services).

Last time I heard in real life about splitting a frontend app into micro services, it was because the team was composed at 80% of junior devs who didn't have a correct git workflow. And they were spending hours fixing git conflicts. "It doesn't work, it will never scale when the team will grow, we should split the app in smaller apps so nobody will work at the same time on the same project".
