Agreed, the potential issue of having different people having different configuration sounds a bit dangerous. OTOH, most issues you mention are true whether you use a db or a plain configuration file - they are just more explicit with sqlite3 (which acts as the model in a MVC organization of your app settings). Incidentally, I am thinking quite hard about those issues (configuration representation, live change/querying, versioing) for internal apps, it is not an easy issue once your app has more than a few parameters.
