Setting Application Defaults in Linux /etc/default

Am I being a curmudgeon, or should /etc/default be reserved to settings for the operating system? I'm seeing systems show up with /etc/default/{company}-environment. The file is typically Tomcat data, but not always. I've also seen setup data for Mqueue. One objection I've heard that makes sense on a technical level is that it does not allow applications to migrate to Containers. Beyond that, am I just carping? I posted this question over in ServerFault, but it isn't getting any answers. What does the group assembled here think? I've looked in the local Confluence docs and it's been this way for like ten years. The technical curmudgeon in me just objects because /etc should not have anything but operating system components. I'd be interested in others' thoughts.
