A simple example is, let's say you're making a small web service. Are you going to use a Clojure framework or a Java framework via JVM compatibility? If you pick a Clojure framework, then all the subsequent choices you have to make, you'll run into the "non boring tech" issues. Has someone already built a GraphQL plugin, a plugin that integrates with the Twitter preview API, etc etc it depends on your project but you'll run into things. If you pick a Java framework, you'll end up running into a bunch of cases where you can't use the "normal solution" for that framework because you're running Clojure.

It's not the end of the world or anything, and for a smaller project Clojure might be the perfect solution. But if it's something that you're trying to scale into a startup with dozens of engineers then you're probably going to pay a higher incompatibility cost for using Clojure.
