maybe it's important photons don't experience time ?
it would be a 'mechanism' whereby a given photon would be able to actualize in a manner consistent with the state/nature of the universe
to clarify:
very soon after the big bang, the universe isn't very big, therefore we have a constraint on the existence on photons existing with a wavelength exceeding the size of the universe
These days, the frequency of such a photon is so ridiculously low as to not be a concern*, but in the early moments of the universe, the population of wavelengths 'permitted' for photons would have been 1) highly constrained and 2) rapidly changing to permit longer and longer wavelengths, this would alter the evolution of the Big Bang over what would be expected for a universe that at all times 'allowed' photons of all wavelengths
* it is also accepted that processes that generate photons via heat invariably produce more and more longer wavelength photons as they heat up (if they heat up) and the temperature merely constrains the highest energy (and shortest wavelength) photons emitted, (I think this is the 'violet catastrophe thing)
but looking at that the other way, how do we avoid an object of a temperature of anything greater than absolute zero from emitting an 'infinite' number of vanishingly weak (and enormously long wavelength) photons ? Well, those infinite numbers are constrained by the diameter of the universe, wavelengths exceeding whatever multi-billion light year length of the diameter of the universe there is, photons are still constrained 'somehow' from being created with wavelengths longer than that. By being 'immune' to time, the incipient photon can 'sense' the current diameter of the universe and either be nipped in the bud or emitted as the size of the universe allows.

The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.
