My personal thoughts... (I may be wrong on a few details, mind you. I'm no programmer)
That would be pretty hard (if not impossible) to implement, because once the game crashes, you're done. Everything related stops functioning right then and there. The only way I would see this possible is for the mod to somehow stop the game from crashing so it can scan for what caused the crash, generate a bug-dump, then let the game blow its top; and blocking a crash from occurring for any reason is extremely unsafe, for game and computer.
I don't think we'll be able to go much further than selective-disable if a mod breaks down.
