Complaining about extra layers is silly. As you pointed out, that’s what EVE is. That said, I can see why some may not like the idea due to the potential tedium involved.
I do think one fantastic positive, is that crew would be a huge isk sink which would help keep inflation in check. The cost per person wouldn’t be that large, but when you take into account all the players paying these fees every month, it would add up to a large sum.
Another factor, is an officer marketplace would funnel a large chunk of money out of the large alliance blocks for their wars. Players who like pve would train up max ranked officers, and relist them on the marketplace, and players (corps and alliances) with deep pockets would buy their contracts.
