A lot of semi auto shotguns dont like low recoil shells. Bout all I can think of. Maybe most semi auto shotguns cant have folding stocks do to recoil springs in the stock. Otherwise dunnoI just don't understand how pumps are more "versatile" than autos. They shoot the same shells. I can swap the barrel on my dad's Remington 1100 just as fast as anyone with their 870.
I can port load my Browning with a full mag just like with any pump. Benelli Novas and Super Novas are even easier yet but are pumps so slower to shoot.
A good auto with good ammo will do everything a pump will do and do it easier and faster.
