It's a good software development principle. Make things that are secure look secure. Make things that are insecure look insecure. This is going to be insecure no matter what precautions are taken, because the source is open and the key is part of the binary, so it should look exactly as insecure as it is so no one assumes anything untrue about this code.
In seriousness, what gives!? Why are these so simple? Surely a development base as large as Chromium's could pick up on something like this.
