I've seen plenty of engineers try to turn trivial functionality like that into a microservice "to avoid version upgrade hell" (quote from one person in a previous job), or bundle what should be a simple self-contained (i.e. no-dependencies) library of functions (i.e. an API) into a REST/gRPC interface service. Microservices fad-following is as bad as TDD in this industry.
