This would be a good idea if all it did was affect the text invisibly — by using patterns of non-breaking spaces, for example. But the text itself is holy. You can't go dicking with someone's writing. A good writer will run down to the printing press and have pages re-set just to prevent a sentence breaking ungracefully onto the next page, and that's just the importance of formatting. It's even worse to go messing with the words and punctuation themselves. That's the kind of idea you can tell was invented by an engineer who doesn't like to read.
