Exactly: at the moment everything that goes into RWBY manga is previously discussed and approved by the CRWBY. That should last at least until the manga covers flashbacks for all the four trailers since it was announced as "the secret stories behind the trailers"...after that if the manga sells well probably they would want to continue but it that's going to happen as well as further publication stays "canon" is not determined yet.

As far as I know/heard/understood.
