It certainly could, but doesn't at the moment. Most likely Gustavo & other 
smartpm-folks aren't even aware of the sqlite extension :)

Indeed. At least with the sqlite db, there IS a version tag one can 
cleanly check against and refuse to go on in case of an unsupported 
version instead of blowing up trying to parse it. So while the format 
obviously shouldn't change too often, changes CAN be handled safely now, 
which is only a good thing.
