When a team chooses microservices I think it's important to acknowledge they have at least made a choice. This alone might be the reason their project turns out better than a more de facto monolithic design. For this reason I think it's important to have "trendy" topics so that they can get teams talking about what they're doing.
You could throw Spring, Git, functional programming and just about everything else into the same bucket of hype but I'd still recommend (at least one of) them.
