Kind of, but is that really a problem? Virtualization provides a layer of security and isolation that containers still haven't (and maybe never will). For a long time just the fact you could run multiple apps on a single server was a breakthrough and for the most part people weren't all that concerned with performance.
Now that it's matured, people are back to optimizing for performance, and this is one of the ways to do that while maintaining the security that virtualization provides. One thing that seems to remain true is that the pendulum of flexibility <> performance is always swinging back and forth in this industry.
