Microservices in Golang are definitely related to classes due to the ergonomic aspects of a language. It takes a lot of discipline in Golang not to end up with huge flat functions. Golang services are easier to reason about when they are small due to the lack of abstractions, also Golang is very quick to compile, so its natural to just add services to extend functionality. Code re-use is just a lot of work in Golang. Golang is not monolith friendly IMO.
