Similar, but more interesting: /usr/share/info/dir

If you have a close look into it, it is an ordinary info-document. i.e.
customizable, partially containing static contents, partially containing
dynamic contents (Note: customizable text! It is not automatically
generated - You can put your company's "intro blurb" into it, if you
like to.)

In a similar situation are the various other "doc" systems (html indexes
etc.)

Also worth mentioning: alternatives, ldconfig and prelink.

Whether you like it or not, the X11-mkfontdir stuff is a very simple,
but effective way of implementing a simple distributed database.

So yes, if you'd want to change this, upstream would be the correct
address to change this.

Exactly.
