A number of deep space probes have had solar reflector attitude control
panels. These use the photons to help stabilize or move the craft to a
new attitude using the photon momentum.

Um? A number of craft have had solar power panels. Which craft
have had solar reflector attitude control?

There have been many proposals
over the years for solar sail propulsion for space probes.

Proposals yes. Examples built, none.
