Following up with MDL-84131, I noticed that there was no existing possibility to actually define "parts" of analytics indicators in mods/ or component.

The use case here is that for example mod_chat is now optionally installed. Unfortunately this means that on a new install the course_dropout target has not indicators related to the mod_chat (compared to the previous situation).

Maybe we should devise a way where indicators can be merged globally as for now the situation is that we manage all this centrally in the lib/db/analytics.php file.
