It's easy to work a Bb into a theme in C without giving too much away.
Indeed, often the VII is not played much, and until it is played at all, you can't distinguish between a ionian and a mixolydian. If a melody is supposedly in C ionian but doesn't contain a VII then you consider it as being C mixolydian and it wouldn't make much of a difference.
That said, I'd like to say that mixolydian modes are extremely common, and arguably more common than ionian ones nowadays! as a proof, think that a 7th chord defaults to mixolydian, and you have to call it "major 7th" for it to mean ionian.
