the idea was toyed with for a fuel idea (so you cant spend day on day in space an adds a boost to the economy) but overall the idea didnt make it far.
As for perishable equips, it may bug the game if said equipment just "expired". Maybe it'll be trteated as destroyed equipment, maybe the effects stay until the ship docks, or maybe it just crashes the game.
Its very interesting idea, and if it were implemented, it would make disco that much more exciting.
