Comment 1 for bug 704482

This is an interesting observation. You definitely have a good point here - the feature is not as user friendly as it could be. These are some core python philosophies which help guide me in the program design, and I think in this case you've identified that "explicit is better than implicit" is not being followed as well as it could be:

Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Special cases aren't special enough to break the rules.
Although practicality beats purity.

Another way to think about it: when a camera has never been seen before, the program could pop up a warning dialog that auto delete is enabled. Please think about such scenarios in the context of different workflows, and then how you envisage such a feature. Please add it to this bug report.
