This is very cool!
As someone who wishes more people got some programming exposure to IBM z and how it works differently than minicomputer derived operating systems (both *nix and Windows count here), I think this is awesome.

Yes there's a hierarchy (with . as a separator), but it's more naming convention than a description of the underlying filesystem. You can create projects.foo.code.bar without having any entity (like a Unix directory) for projects.foo first.
I was trying to get around it on SimH, with the B5500 version. Definitely deserves the name.
I think MS-DOS comes from CP/M which was also sort of rooted in the minicomputer era.

Most People seem to at least know that mainframes and Cobol exist, even if they've never seen them. IBM I (and its primary language, RPG) are similar in importance to the global economy and just as different from Nix and Windows systems, but they seem to be far less known.
They're also far easier to get access to, there's a free modern system that you can get an account on at pub400.com. With Z/OS, you're stuck with Hercules emulating some ancient version from the 80's which there's barely any documentation for.
IBM provide free 1-year Z access via the Zxplore program.
