AOA indication has always as far as I know been considered an option on
light civilian aircraft. There are costs involved as well as performance
testing to determine optimum parameters....another step in the process.
The main reason I believe is the fact that light civilian airplanes fly
in the area of lowest performance where the raw data already existing
using basic instrumentation is sufficient.

They're somewhat more common on experimentals (i.e., homebuilts), and
I agree, I wish I had one on even my lowly Cherokee.
