It has more to due to leveled list conflicts than anything else. I had several gear mods that give the Gunners all kinds of different shit and it's a careful balancing act to get them all to work together.
Honestly I think the Gunner's leveled lists are bugged in vanilla to begin with. Start adding mods and shit can go sideways very quickly.
Ideally each mod that added gear would add a small area where you would have to fight some enemies or solve a puzzle to actually 'earn' it. But most modders who mod in gear don't know how to do CK world-building and vice-versa. It's not being lazy, it's just specialization.
