That's not really true. the average user has no clue what a file format even is, much less what a CRX is. And to be entirely honest, it's not fair to expect them to know what files are safe to just download and run. So, we made the decision to protect the average user at the cost of an extra command-line flag or a drag-and-drop operation for developers. I think that was a good trade-off, but you're certainly welcome to suggest something better.
