I've recently wrote about the subject here, but I wanted to ask this community specifically if there were any thoughts about this. To recap, I think there's a value in using the directory hierarchy as a key-value hierarchy for program configurations. I realize that there are downsides, but I think that especially in a unix-setting it would be worth playing with the boundary where directories and and where files begin.

So what opinions do other people here have? Could this help improve the situation with configuration files or is just another case of XKCD #927?
