No, but it probably keeps you from being a great developer.
I've worked with a large number of people at a large number of companies, and the difference between the solid "B" developers and the amazing "A" developers is that the amazing developers are passionate about technology and coding, and always have a side project of some sort going on. They are excited to learn new languages/frameworks/ideas and bring that added knowledge to their day job with great effect.
