If you ask me, it's really a shame (security-wise), BUT having a kind-of-secure TouchID is WAY better, than having absolutely no security (i assume that people that didn't use any passcode now use touchid).
We (and Apple) need to educate people, that it's not the perfect and completely secure solution.
