This is good advice.

Within our team we use 5 different mainstream languages to accomplish different goals within our system.

We handle a single service, but we manage the full stack using many different languages and frameworks.

We don't have to be expert in the frameworks, we just need to be experts at what we are building. And we learn each framework to the point where we can accomplish that.

The "selling point" that we value is to be able to deliver.
