There is no deal--or at least there wasn't...
It was a total non-issue for many years as part of the takedown process of one of the most popular .22LR pistols on the market in the U.S.
Then a particularly polarizing polymer pistol became common and it also used a trigger pull as part of the takedown process. Suddenly the need to pull the trigger during takedown became problematic and dangerous.
Frankly, I think it became a convenient way to villify a particular pistol that many strongly desired to villify. If there is a deal, that's about the long and the short of it, as far as I can see.
