I agree as well. In case of no prj or other CRS information and no default CRS defined, it would likely be best if the CRS was set to "Unknown (Assumed Geographic)" or something like this. It wouldn't be too hard to add this to the current CRS db as an additional available CRS, and when users have a quick look at a layer's CRS, they will instantly see that they have to properly define the CRS if they want to use the layer properly.
