> My point is that if it were designed from the ground up with the hard security boundary in mind, would we have ended up with containers in the first place?

Yes. The only difference is the Linux based systems and tools as opposed to Zones or Jails were the first pivot to a developer focused view rather than that of the sysadmin. This utility is why containers gained critical mass, not because the security focused foundations of other implementations was an impediment.
