this is not really what the article is about.
yes you can read man page, you can find there all possible locations of config files. yet you still don't know where config file is stored. you have to check all the possible locations.
also if there would be some standard so you can query app for its config files, you could make automated backups easily. at least much easier that now.
of course I understand this is completely unrealistic, in software world everyone will do whatever they want..
honestly only thing preventing me to buy bidet is that vision that after every other toilet visit will be disgusting.
long time ago I spent some time in japan and having integrated bidet in every toilet was amazing, but for me it is all or nothing, either want to live in the world of bidet or in the world of toilet paper, not in the middle.
