From a photographic stance there is no real desire to directly edit raw files in a normal workflow. It isn't needed, and it really serves no purpose, so typical software doesn't include that kind of functionality as an option. However, that doesn't mean it isn't possible to still go in with specialized software to do just that.
Which is a big reason why I don't really care all that much for the stance that various publications have been taking of "we can totally trust our photographers are being ethical because we're only taking raw files... Because this totally couldn't be bypassed..." as they're claiming they've done something to change things, without actually having achieved much of anything. Those who are truly dishonest about stuff are going to be pushing to find a way around it, and guess what? Googling really isn't all that difficult.
