Feature suggestion - using compressed public keys by default

As far as I was able to check, the blockchain wallet uses uncompressed public keys by default. Since it is very popular, a lot of people are using uncompressed keys. If you were to switch over to compressed public keys, each transaction sent from the wallets using those keys would be smaller, meaning the future blocks could accommodate more transactions. Just a way to be forward thinking and "greener" .
