Kafka follows a "fully compatible model" and new features are always optional. We have extensive compatibility testing to make sure rolling upgrades are safe and painless. This investment in compatibility allows us to reduce the effort needed in maintaining old versions (Security CVE is the obvious exception, as well as data-loss bugs).
Not every OSS project has the same model, but it has worked for Kafka for years now (since the awful upgrade from 0.7 to 0.8 in 2014).
