Well... the converse is true as well. I've already got a well polished CV (I usually keep the resume mostly identical for my job applications, while I customize a summary header and I write a dedicated cover letter), an updated LinkedIn profile, a website, a blog, a Stack Overflow jobs profile... and I need to enter that information AGAIN in your system, which is possibly slow, hard to use and/or requires registration, just because your process says so? You'd better be a great company to work with and/or pay very high salaries, or you won't get my attention. Today the developer market is largely driven by developers, not by companies; make sure your practices are not driving potential good candidates away from your company!
