While this may be the case for the Navy, the Army's standards for recruitment still haven't changed all that much it seems. With deployments in the Army still at one year and change, I'm surprised the article doesn't try to make more of a distinction between the needs of the different branches. The Navy isn't the Army.
These petty officers are already trained, been in for a few years, have some significant expertise (hopefully), and want to remain in. They may lose some good people this way. My only hope is that the screening process is conducted in a manner that will just cut the lowest common denominators out there.
