I'm not really sure that is the case at all. VMS had versioning file system that had support for multiple file types including stream, sequential, indexed and relative. It had a very different security model, four levels of processor access (unix there's kernel and userland) and it had very different networking capabilities, including clustering baked in (in 1983).

There's deep VMS heritage in Windows NT: both VMS and NT were written by David Cutler.

Agreed. I've only limited experience with i, but more with z. After using them, the other OSes you might use start to look and feel pretty similar to each other.
