Yes, but a cheap film camera with ISO100 loaded will display orders of 
magnitude less noise compared to even a moderately priced digital camera.

But the data never exists as a whole in the first place in cheap cameras. 
The demosaic/compression chip will work on groups of lines at a time and 
spurt them out to the file-write buffer.  If you tried to simply pass the 
raw data through you'd need a much bigger buffer and possibly faster 
file-writing electronics (unless you're happy to wait 3x-6x longer for each 
write).

Also they would need to include some RAW conversion software with the 
camera, which needs writing.
