The last thing I need is Snapchat to say "We need access to the facial scan for new video filters!" and then using it to measure microexpressions in response to ad displays.
Haven't checked, but I assume that (like TouchID) they do provide APIs to use it for authentication, but they refuse to give any more data than that.
That's what I want it for.
TouchID isn't very useful outside of fingerprinting. The dot projector I could see a wide variety of really neat, innovative uses by third-party devs if it can be made accessible.
The moment 3rd party devs have access to the scanner, it'd be siphoned off by somebody's ad framework and then sold for biometric ad targeting in nearby stores or god knows what else.

For room mapping it seems like ARKit should cover a lot of use cases. The tape measure demos I've seen were solid. But IIRC ARKit has a lot of stuff built around identifying flat surfaces like that, it can't help you so much with arbitrary objects.
