If the AGL is able to be more effective in achieving the goal with less ammo expended per weight, it might well ease the burdens. And are you really sure that pockets were liquidated as quickly as possible?Soviet armies in the pockets were being annihilated about as quickly as it was possible for the Germans to employ the force needed, with hunderds of thousands Soviet soldiers captured. Another hundred, even thousand of Soviet soldiers incapacitated is a drop in the bucket.
In the same time, automatic grenade launcher adds to the German logistical burden.
You're comparing some pretty wildly disparate things. The reason there was no assault rifle in 1939 due to the conceptual issues around it; technically it was possible and indeed already invented in some cases, but not adopted due to doctrine issues.Same reason as why there was no assault rifle already by 1939 in service, why there was no LR Spitfire and Tempest fighters until too late, why the Merlin Mustang was almost too late, why US manufacturers didn't jumped on the opportunity to produce Mosquito under license, why the 76 and 90 mm cannon was as good as too late for ww2 on US tanks, why 6 pdr ATG was a year too late, why KV-1 didn't got the 85 mm cannon in late 1942, lack of quantitty and quality in German artillery - people in charge didn't saw the need.
Tempests were not technologically possible in 1939, while LR Spits were but were not developed as they were supposed to be only short ranged interceptors. The Merlin Mustang was ready in a shockingly short period of time given that the original design was conceived only in 1940. I could go on with each of these, but ultimately there were just different reasons for nearly each.
