Might be you speak of the problems when computing one-particle relativistic wave functions.
If e.g. particle number is conserved and you consider a small amount of particles in a scattering process, and you get a non-vanishing cross section to many many states, then a frequentist interpretation for the transition amplitudes is sensible.
I put the square root in big quotes anyway - of course, it's not even a scalar object I speak of.

>The fiber bundle description works on the classical level.
Yeah, pretty sure that's how people think about it in any case. Good thing is that in path integral quantization, you don't have to pass to operator valued fields at all.

Super minor Language issue: Not sure if that's relevant saying, but
>...the fact that gluons have self-interactions, but photons don't.
catched my eye. Be aware that while there is no non-linear term in the EM Lagrangian there is still photon-photon interaction,
pic related
