Looks like this is a change in the API? Sorry I didn't catch this when the first patch landed.

We need to figure out the deprecation process for old API features. I propose we detect if someone's calling it the old way, and correct for them, but also write to console.error that it's deprecated to do it that way. Add a comment there giving the date of deprecation. X number of months later, we can replace the soft failure with a throw. Sound reasonable?
