My understanding is that we aren't supposed to change electrical sources during fueling, but are we also precluded from deselecting the APU gen and spinning it for the packs while fueling and leaving it on the GPU until that's taken care of?
I opted not to start it and if there's nothing against doing so, that decision will haunt me for the rest of my days.

'MAY NOT' still sound optional to me, and I have been doing it all the time, who knows how long it takes for those fuelers to slack off down there.
Then next sentence says: 'DO NOT' start the APU during refueling/defueling if an APU shutdown or a failed APU start occurred.
That I wont mess with! But it also proves that above is optional. Just my 2 cents.

But...
At republic we had similar language in our manuals. It previously was an Embraer suggested limitation to not start the APU or turn it off while fueling. Embraer revised their manuals either late last year or earlier this year, which removed that limitation (timeframe has all blurred together so I can't remember exactly when...). So we are able to start and stop the APU at any time while the fueling process is going on.
We however still have the limitation of not connecting or disconnecting ground power while actively fueling. I believe that is a grounding issue.
