I've worked in a place where test suites started in postman because of the lack of skill in QA. For us, the fact that you end up writing "code" in postman meant it had a learning curve anyway, so it was a really short sighted win. For everyone smart enough to write postman code, especially postman code that leverages the scripts and storing variables, a simple test project set up by a dev is going to be very worthwhile. Postman doesn't have a linter or compiler, and it doesn't enable easy viewing of changes in source control because it's just one big json file.
