And as to the earlier convo about IC in OOC, yes there are IC methods that are preferable to OOC announcement of lolrandom deaths, like turning on suit sensors, but suit sensors themselves are lolrandom, as far as I can tell. If you don't have a habit of checking to make sure they're on every round, which takes a while to develop, then you're liable to get killed with them in an unknown (to you) state. And yes, there are times when using OOC to announce "och, teh carp" when the radio is out is bad. No IC in OOC is ideal. But there are rare times when I think it should be acceptable, though certainly never preferred. It was the absolutism in your post I objected to.
I am of the opinion it should be almost totally absolute. That's how the rules are written on the Wiki. I think it totally changes the atmosphere of the game when you've got a bunch of commentary about the round going on in OOC. MAH IMMERSION and all that.
Maybe if its an extended or sandbox round, without any admin event going on, it's ok to use OOC to get yourself cloned or whatever. Just because you know you're not going to be screwing over any antags, and those rounds tend to go for a while.
Furthermore, in antag rounds OOC-ing for cloning can really screw you over in the long run: if you happen to be the antag's target, he may employ additional measures to ensure you don't get cloned (decapitation, de-braining followed by cooking, spacing...).
The main thing we need to do is to make a habit of checking Crew Monitor Computers every couple of minutes, so if you die by accident in, say, Library, your corpse won't just be ignored (HAPPENED TO ME - I got slimed to death in Chapel, hauled off to Library and... promptly forgotten). If someone forgets to turn sensors to max, he's either an antag or gets on the wrong end of natural selection.
