I generally agree, but there are some decent use cases for one team to have multiple services micro or otherwise:

1. when the requirements are better served by a different language/location/environment/platform.. or by deploying a 3rd party app.

2. some of the services need to quickly scale up and down, and you have enough traffic for it to be worth it.

3. if you have a tight SLA for parts of the app but not all of it.
