Awesome, thanks for this @diosmosis .

@sgiehl to get this into core do we need to trigger a new release and update it via composer?

[tsteur]

We'll basically need it to get tests working in travis as the tests use this method.

[sgiehl]

@tsteur yes. a new release will be needed. will this be required in 4.x-dev branch or only 5.x-dev?

[tsteur]

Ideally in 4.x-dev so the tests start passing sooner 👍

[sgiehl]

Ok. Will do that now.
