This is 6.x material to me for exactly that reason — we have changed the defaults for functions with optional behaviour before, but I think this one has more scope to break applications due to the potential for data loss when users have used limited database columns (and I suspect a _lot_ of uniqid() users are storing the result in a database). Since there is a need for "unique" values, would we be better off considering bundling the uuid extension (or something similar) to provide a simple way of generating UUIDs? No BC considerations then, and it's probably a better option for unique identifier generation regardless.
