I wouldn't worry about it too much, i had pretty rare bedwetting occurrences withou the cpap machine,, no matter if i was diapered and had been consistently wearing at night for a long time. It seemed once i started using the machine and got better sleep that i was more likely to wet at night without waking up or during a sort of half awake state where i barely remember waking up at all. If anything i look at it as a legitimate reason for me to have a need for diapers. Im now in a situation where i never sleep diaperless for fear that it will be the one time i wet myself. I will also mention however that within the past year due to fairly significant vision loss, and not necessarily have the ability to easily find or get to bathrooms as fast as id like, that ive gone to wearing during the day also. This makes my life far easier. You be to look at it like this, if using a cpap, only causes u to need diapers at night, than thats a hell of a lot better then a some of the other problems ive read about from people using cpap, or the risks of not using one, which are far worse than a wet diaper. I'd much rather have better sleep, than worry about the risks from not using it, such as higher chance of heart attack, stroke, glaucoma, although in my case i already have glaucoma. But im sure u get what im saying. Needing diapers while using a cpap for better sleep is like the best worst effect u could have.
