Not writing to raw files is *not* a bug, it's a design decision (feature, if 
you prefer)...

And in my opinion a good one, every now and then there's a bug report about a 
program corrupting the raw files sufficiently that they become unreadable for 
other programs. "Every now and then" sounds like it's not a problem. But it is 
if that makes you lose your images. I treat raw files like the old film 
negatives: only (re)touch them when absolutely needed and knowing what you are 
doing.

The exact format of most raw files is only known by the camera makers. How to 
read the information is more or less deduced by programmers of 3rd party  
programs, but that's not always enough to reliable write to raw files.
