Sure, because it was introduced in 1.3. We should make the decision to drop 1.2 support if we want to move forward and support 1.5+ since it's not going to be compatible unless we vendored in the newer version of `url` and loaded that in, which doesn't sound like a good idea to me.

I'd argue that we can safely remove 1.2 support. I can't imagine many people still use that in production.
