Yeah, I don't think it does!

I document things like this for a living, and before I did that, I
used to implement servers for significant mission-critical systems,
among other things.

In my professional opinion: no, it isn't.

Long ago, >20y ago, I bench-tested systems for a living. This is the
first time I started studying filesystems, partitioning systems and so
on, and writing about them. This is around the time that things like
FAT with long filenames, FAT32 and so on started to appear. My systems
had to share files between DOS, Win3, Win9x, NT and MacOS. I therefore
had to become an expert.

A hobby of mine was to point out in print how companies has supplied
systems with inefficient disk layouts.

Occasionally an angry supplier or vendor would come to me and complain
about such things. They would talk about things like how putting swap
on the outer cylinders of a drive caused a performance drop and other
theoretical considerations.

It gave me considerable pleasure to set up demonstration systems and
prove them wrong, to their face.

Things have changed considerably and I no longer consider myself an
expert in this, merely well-informed.

As such:

I think what you are doing sounds gratuitously and pointlessly
overcomplicated and likely to cause problems.

As it is doing.

Just saying...
