The problem with that is that password derivation is entirely reasonable and encouraged. It's what PBKDF2 does (the "KD" stands for "Key Derivation"). Securing your passphrase with a few thousand rounds of bcrypt and salting with the domain is a great way to strengthen it, since you don't have to trust any shitty MD5 password storage mechanism the site has, the attacker has to brute-force bcrypt to be able to get your master passphrase.
