As someone who just looked this up to confirm this and reply to someone else here, the docs[1] are fairly ambiguous in this respect. As someone soliciting feedback on the docs, that's a good spot to clarify. :)
P.S. I considered submitting a PR, but I don't know enough about rust yet to accurately phrase it.
I am ridiculously tired, after burning the candle from both ends for the last few weeks to get this release shipped. In the last four days, I've written almost 1700 lines of docs. I make mistakes sometimes :)
