It wasn't until we had reliable ammunition that improvements in gun blanking, especially pistols, could more quickly evolve. I'm sure that Steve C would concur that "our guns are only as good as the blanks"
Regarding the crimp, it also keeps the powder retained and burning longer than wads thereby resulting in consistant pressures especially critical for semi/full auto gas operated guns. Without that the 1/4 and solid plug loads (9mm solid plug only 1-2 grains of powder!!) would be even more tempermental.

I agree there were blanks in the early 1900's but they had paper or wood bullets. Stembridge made blanks in the 1920's but Joe Swanson set the bar for consistent and reliable blanks in the film industry.
