"lock-in" potential should be measured in how difficult it is to escape a platform/system/framework.

E.g., if I become unhappy with k8s on Google Cloud, it's easy to migrate to aws. If I become unhappy with k8s, it's easy to migrate to Mesos. If I become unhappy with Linux, it's easy to migrate to FreeBSD. If I'm unhappy with Lambda, it's easy to migrate to cloud functions, or a self-hosted FaaS.

Some systems require major rework, or are just otherwise impossible to migrate off (probably by design). Those are the systems to be careful when adapting.

Evaluate the "exit friction", build something useful, and stop worrying.
