This is true for many new waves of popular technologies.
1) A new technology or method becomes popular.
2) Developers find new advantages in using the technology.
3) Understanding of tech and original advantage is somewhat lost.
For example: containers are now widely used as part of a scriptable application build process, e.g. the Dockerfile. There are probably many developers out there who care about this and not about how containers are run and how they interact with the kernel. And for their use cases, that is probably the thing that matters most anyways.
A down side is that people feel like they have to bundle an entire Linux rootfs because they think of a container as a lightweight vm: if they thought of it as a os process running inside various namespaces, they might be more inclined to only ship what they actually need.
