In general convention doesn't work so well if you're not really into the system. I.e the casual users.

Convention means that behaviour depends on not just what's present but also what's not present. So it is of course missing some of the explicitness. For the directories, you need to understand which directories to look into and in which order they are taken into account (for systemd this is hard enough that's it's best to be tool assisted).
