Can you show an example of how you use SQLite for _config_ files?
I've shipped a product that used SQLite, and we actively removed configuration from SQLite. It was a lot easier to diagnose issues when configuration was in text files, because non-programmers could kinda-sorta understand them without needing to learn how to use SQL.
Given what I know about it (single file, no auth, and such by default) I sort of understand the ”file” part I think. But not the ”config” part.
