Why is "Crescendo pedal" trending?

Wikipedia Overview

A crescendo pedal is a large pedal commonly found on medium-sized and larger pipe organs, either partially or fully recessed within the organ console. The crescendo pedal incrementally activates stops as it is pressed forward and removes stops as it is depressed backward. The addition of stops, in order from quietest to loudest, creates the effect of a crescendo. In actual use, the operation of the crescendo pedal usually does not move the draw knobs or stop tabs on the console; the stops are electronically activated inside the organ. Often an indicator light or lights will be present on the console to inform the organist of when the crescendo pedal is activated and how far it is engaged. The crescendo pedal is located directly above the pedalboard, to the right of any expression pedals that may be present.
