If and only if you live near an Apple store. Otherwise you might be without your machine for a week or two during that period: that is a serious cost for many people in our profession.
That's certainly a valid concern; I have never been in that situation so yeah that could be trouble. Aren't there typically local repair centers that do authorized repairs? If not that's a huge oversight even if they only allowed battery swaps. That said, I have a 2006 MBP that is ancient and still works when wired to power even though I can replace the battery it works fine as an email/web browsing headless with a monitor.
