I'm also in the camp of not disconnecting the battery cables. Some
manuals say when jumping/charging to ground to the engine/body and
with only the positive connected to the battery and I tend to do that
on more modern cars.
I once saw a frozen battery explode. Thankfully my Dad didn't get
hurt but connecting to the dead battery first seems like it would be
safer so you could take cover or be as far away from it as you can be
when a charge is applied.
