What effect does a tuner have at the antenna?

You can take advantage of the "information" provided by the

observing the maximum available output power.
The point is, it can be monitored *at the antenna*
thus proving that a tuner does indeed have an effect
at the antenna.
All canards have a kernel of truth in them. My guess is that someone
observed that an antenna "tuner" would "tune" a wide variety of oddball
antennas to transmitters that were looking for a particular impedance.
Then to simplify matters, someone said "the transmitter doesn't care
what is on the end of it, so long as it sees that 50 ohms impedance.
It's a short drive from there to "the tuner has no effect on the antenna".
