This isn't a protocol change, so it's not really a big deal. It's basically a strongly worded (coded) suggestion from the core developers to discourage micro-transactions and blockchain spam (SatoshiDice, encoding data in the blockchain, etc)

This is the way it should be since miners bear the cost of every transaction in the form of computing/network/storage resources.
