I've always felt slightly off about creating an arbitrary unique value unrelated to the actual context of the data when there is already available a way of uniquely identifying rows that only uses actual system data.
Also, by default most DBs create an index on the primary key, which is a bit meaningless with a created single key when most/all data access will still be by what would otherwise be the compound primary key. Just means you have to create an additional index, i realize, but there ya go.
So no real technical show stoppers, just a couple of things that kinda run against the grain for me anyway...
