Thus, after the photon goes past a certain point, there are no experimental consequences whatsoever, ever, to the statement "The photon continues to exist, rather than blinking out of existence."

One shouldn't form theories about a particular photon. The statement "photons in general continue to exist after crossing the cosmological horizon" and "photons in general blink out of existence when they cross the cosmological horizon" have distinct testable consequences, if you have a little freedom of motion.
