I thought so too, but found this reference to a Version 1 mkdir:

That is the command in man(1) and always existed. System calls documentation live in

I recall reading a Version 6 or 7 man page about mkfs that included the ability to
populate a file system with some directories, and I thought that implied that users
couldn't create directories. The man page referenced above hints that mkdir is run as
the 'system user', presumably root, and becomes the owner of new directories.
