I mean, that's what you'd expect from an OS that was originally for teaching, right? A worked example of the fundamental parts common to most other unix filesystems, just as I would naively expect the minix scheduler to just be round-robin or something, etc.
Well, that was especially true for Minix 1 and 2. Minix 3 is purportedly a production operating system, and ships in every Intel CPU for the last decade or so, right? So while admittedly it may not have significant filesystem needs, it is not purely a teaching operating system anymore.
