I don't think an attempt at small scale saturation bombing would be useful, since everyone is just carrying one or two, they'd need to make their shots count better. Really, M72 LAWs or similar would do this better, and would also be better at disabling light vehicle armor and fortifications and structures.

40x46mm isn't like a mortar shell or anything, but assuming you make sure to aim them, they're enough to work with for direct infantry combat, and if you've got something emplaced feeding them with belts then they can make up for their mild payload through volume (though typically such weapons end up using further reaching 40x51mm MV and 40x54mm HV grenades).

There's also six shot 40x46mms you can carry with you, though that tends to preclude you from carrying a proper rifle or carbine, so there's some mixed feelings on them. Also you'd still want to properly aim your shots with those anyway.
