If everything is plastic, you shouldn't be required to bond. The risk of current in the water itself is IMHO negligible in a house.
Having a dielectric union and not using the underground pipe as an electrode is a good idea. To the extent that we should have grounding electrodes, we shouldn't be confusing them with plumbing.
I don't see how GFCI or AFCI tech changes the need (or lack of need) for grounding. You want to provide a well controlled path for low current, high voltage upsets ('static', HV leakage, etc.)
To ground or not to ground was seriously debated at the start of electrification. Soares Book on Grounding and Bonding had some history on this subject.
