Sometimes it's faster to implement certain features in another languages and deploy it as microservice instead of fighting your primary language/framework to do it. Deploying microservices in k8s is as easy as writing a single yaml file.

Makes sense, though 15 different languages?

I am not privy to the details of the case, but a rule-of-thumb I heard once is that if it's far enough from your core, a SaaS can be used (obviating the whole question), and if it's part of the core, start by developing it as a separate functionality before moving it to another service.
