Moisture was main concern, I wasn’t sure how it would work in this situation since that part of the roof will have no air seal with drywall

how is it normally done in attic spaces if someone wants to insulate the roof in a traditional house using batts
Normally you have conditioned air on the inside to worry about, so unless you are heating the space you are just storing some batts in that space. The drywall on the inside is about keeping moist house air out of the insulation. If it is a closed space there is no house air in there.

Ok thanks, I will have a couple of access doors though that will be opened from time to time, but hopefully they won’t have any major air leak while closed

but the roof is vented there anyway so maybe that wouldn’t be a problem anyway, i guess they would be no different than pull-down attic ladders
Attic hatches and doors like yours should be sealed as good as an exterior door.
