The suitability of ones wife always used to be an important factor when assessed for promotion. I don't think there is a problem there
P.Nav please do not bring up the subject of ISS before I have had at least a breakfast beer. The AOC once asked me how I had managed to get promoted without even starting this ridiculous time consuming course (not his words). I asked him if he wanted the truth. He replied in the affirmative. I explained that it just required a tick to be placed in the correct box on my flight commander's 'chaps qualifications' board on his office wall.
I forget the reply.
