These things briefly came out I think to target the California market before bullet buttons and other things (some of which have also since been banned) allowed people to continue using semi auto firearms they preferred instead.
The problem is that when semi autos are restricted or banned capacity tends to get banned too, and progressively the left over capable firearms become more restricted.
Shotguns for example often get capacity restrictions in the 3-5 round capacity limit for example, and have quickly been targets of additional legislation in all places that banned semi-autos first as pump action shotguns were often quite popular, which means they become the go to for good and bad actions alike and have only a slightly reduced rate of fire of a semi auto (though much harder to use if wounded or one handed.)
Australia, England, many EU nations, I think even some states with assault weapon restrictions. MA I believe has a 5 round capacity limit on shotguns before they are considered an assault weapon, which is well below the limits for other types of firearms.
And the Federal law included guns like the street sweeper, and striker, which in all reality is less capable than a semi auto shotgun, and the only feature they had was a drum, some of which required manual winding and so would be slower to reload.
I know this is a rifle and not a shotgun, but I believe the same principle applies.
The only point at which this would be preferred over a semi auto is a point at which it will be quickly under attack too because semi autos are no longer the primary focus.
I like pumps, and dealing with some greater restrictions on semi autos have made some tricked out pumps in configurations I could not do in semi auto. However in gun fights one of the things injured most frequently is the hands and arms as they are out front and close to the weapon that an opponent is often fixated on. If your weapon requires both hands to operate or even cycle then you are immediately at a major disadvantage if one of the most common things to get injured does get injured.
