It's so annoying - on Windows, you can't even prevent Chrome from complaining every time you start it up when you have Developer Mode (and unpacked extensions) active. On Linux it doesn't, fortunately. I just want to use my own extension and it's not something that others would benefit from.

I even tried to put my extension up on the Web Store just because of this but I gave up once my (obviously valid) credit card got rejected. Now I just live with it.
