My apologies. I misread your intent. I thought you were suggesting that images should be sent as raw octets for the image, rather than picking a compression format. But that raw data is extremely large, and therefore would have horrible impacts on bandwidth and latency. That said, you're right. Trying to be clever about what people are sending results in a lot of hidden complexity and bugs of various forms.
