I'm ok with this, but this is potentially a breaking change for some folks, so let's wait until the next minor release (tomorrow or Wednesday probably), so that we can chat about this before merging.

I'm guessing it would generally only break tests, but still...

Personally I'm 👎 for this, I think it'll be a significant breaking change for lots of people because of tests, I also think it's a bit uglier for little gain.
