This would be super annoying.
I disagree. The most annoying thing related to corpses is how fast they can pretty much 'evaporate', sometimes on the very next turn after picking them up. That's ridiculous and that's the really annoying stuff.
This RFE wouldn't make it annoying. How often do you actually carry corpses around with you until they rot away? I only do that in case I want/need to eat that corpse but can't since I'm bloated already.
How many corpses do you carry around as a food supply? I'd say no more than 3 since rations are very common and provide better satiation value at a fixed weight of 100s or 200s.
Consider that you get one bone every 30s or 60s of corpse weight. This is perfectly acceptable, I don't see a problem with this RFE, it would be a very nice feature, bones are light and stack. What's the big deal?
I would also simply drop the excessive bones, though occasionally they are useful early on when you find a blink dog and wish to tame it so it can summon more of its kind in combat. This in turn gives a chance to generate a useful corpse.
However, if most of the people actually vote against this, I will post an RFE that sets a minimum time that has to elapse before a corpse starts to rot and an additional, longer period of time before it rots away.
Something has to be done about corpses rotting on the spot, right after the creature dies.
