It could be, but I doubt it. I think I would rather error on the side of general safety. The time it takes to arm an automatic is insignificant, there just aren't the fun old fast-draw duels like there were in the old days. However, we all know that an armed gun will occassionally discharge when dropped, bumped or when going about life (like in a theater). There is no need for anyone to carry a pistol with a chambered round. It's like running with scissors, it's begging for an 'accident'.
One can make a strong case for NOT carrying a weapon with a chambered a round (accidental discharge being primary, time savings being near zero). I have talked with several cops, and I have never heard one say "I drew my gun and immediately began to fire". If you feel you are in danger, draw your gun and arm it. In the case of Houston, TX TWO officers had a suspect unarm them, and shoot a total of 4 officers just about a month ago. If the suspect had to arm the pistol, there is at least a 50% chance that 1 of the 3 wounded officers could have shot him. Therefore, I cannot make an arguement to always carry a pistol with round chambered. It's an accident just waiting to happen.
How are the officers supposed to fire on him when they have to chamber a round first? He'd be shooting while they are occupied with their weapons.
There is not always a moment to spare when lethal force is needed. Sometimes assaults occur without warning, and in that moment, each second is critical.
Would you explain *how* this happens in a modern firearm?
BTW, you may want to reconsider your use of the word *we* in your asertion, since I don't know a SINGLE person familiar with modern firearms who would agree with that statement.

I'm not aware of ANY CCW instructor, firearms expert, state or federal weapons expert who would agree with that. Granted, there may be a few out there, but 99% of the folks who have studied the matter as their life's work, disagree.
