I had a few CVN CO's and XO's that had SWO pins, on the CVN's I was on it was required for the surface designator LDO's to earn their SWO pin and some weren't too happy about it.
They must have earned them before SWO's limited eligibility to earn them ~20-25 years ago. I figure if you did the work you rate the pin, but this decision came from the same community that got rid of their schoolhouse so I'm not surprised they took their shiny toy away from those unworthy aviators that happen to command the largest ships in the Navy.
