Does gait recognition (and body tics / unique movement style) not make this moot?

My sense is that facial recognition is a stop-gap and soon to be superseded, because the tech is there for more holistic 'reads' of a person - And that those subtle things that we humans can't see are actually plain as day and as clear as a fingerprint.

If we cover our face, then the data collected on gait etc. will be more than enough. If we adopt a different gait, then the data on other foibles and styles will then give us away. Etc. (we can't hope to disguise all of these at once)
