In a past life as a product development engineer, it was not an infrequent event to be asked, presented or even ordered to create something that proves the above devolution theory.

One example, was attending a cross functional meeting on improving UK instruction leaflets for wiring mains powered products, so the usual ideas trotted out,

Better diagrams
Colour diagrams
Photos
Bigger text

and having the text repeated in Braille for the blind or impaired vision.

With a straight face I pointed out the cost proposition of of punching dots in the leaflet versus the number of blind or impaired sight electricians with a guide dog capable of barking out the wiring colours would be a very small and rapidly decreasing segment.
