Unlikely. It theoretically could be made ACID compliant (all it needs
is an OS-guaranteed atomic move/rename operation), but my point is
that some things don't _need_ full-on databases. Financial work *does*
(if I'm accepting money from people, I'd better make pretty sure I
know who's paid me and how much); bookmarks usually don't. Also,
bookmarks are the exclusive property of the person who creates them,
so it's helpful to store them in a way that can be edited; with money
movements, you often want some kind of indelibility guarantee, too
(you can't go back and edit a previous transaction, you have to put in
a correcting transaction). Different tasks demand different storage
schemes.
