I find it odd that you feel put off by the single choice of database, while also arguing that users shouldn't mind being tied to databases in general. Surely using SQLite when your setup is better suited to PostgreSQL is a less harmful trade-off than the case where files would have been better suited to your system/requirements.
I suppose. I have never understood an aversion to databases in general (though I do understand the general concept that the filesystem is, in a sense, a perfectly fine database for many purposes).
