Missing a valuable feature

Ive been using this with good results for years, but a feature that was most used when it was first introduced has since taken a hike with the introduction of support for many currencies. I of course mean the silent identification! You could at one point set the sound switch to silent, and the phone would shake to let you know if you had a 1 or 5 US bill. I used this a great deal in loud places or even a library. That long-missed feature Im sure would benefit deaf-blind users of iOS devices.
