In the last couple of books there have been mentions of the ICN possibly having to resort to impressment of sailors due to running up against the limits of their volunteer sources. I believe that was before the mention of the high levels of motivation and enlistment coming out of Zebediah, and the uptick in recruiting in Chisolm and Tarot. With the full intergration of Chisolm into the empire, my guess is that also reduces the stresses placed on manpower, giving them a short reprieve.
I like the WINS program, and could see it going forward with someone like Howsmynn to push it. I actually expect he would be the one to bring it to the inner circle as an idea. Of course, all of those gentlemen with their cushy quartermaster jobs will probably howl and whine, but it would make for some interesting scenes. Probably nothing as spectacular as what Nimue did to Captain-my-shoulder-my-shoulder.
