His point was that the stall speeds marked on the ASI (Vs and Vso) are
applicable only at 1 G, maximum gross weight, and the appropriate
flap/gear configuration. That's why an angle-of-attack indicator
would be nice.


Well, in a way, the airspeed indicator IS an angle-of-attack indicator.

I've seen this
The airspeed indicator is an airspeed indicator ONLY. It is not, and
should not be thought of as, ANY sort of AOA indicator. If you fly
long enough, this will kill you.

Stall AOA, for example, is a constant. The airspeed occuring at the
stall AOA can and will vary, depending on wing loading resulting
primarily from the weight loaded into the aircraft or loads imposed by
maneuvering the aircraft.
