These days, almost every resumé is processed through an ATS. Depending on how outdated their code is, you could get spit out for using "UX" in a job description, while applying for a job as a User Experience designer. (True story: I ran mine through an ATS simulator, which asked me if I was a UNIX developer).

You must work in some of the few places that use a human being to screen resumés. Most don't, so they don't care how long your resumé is, so long as it's stuffed with the right keywords.
