I'm not so sure. How many people are motivated to dupe your fingerprints to get into your iPhone? How many of those people could conceivably get into your iPhone through other ways?
Fingerprints are a nice way to keep almost everyone out of your device. And for the rest, well, I really doubt some other locking mechanism would've kept them out.
