Collaboration in Rush still not a feature

We are looking at cancelling several work accounts for Adobe Rush as it still does not have the ability to collaborate with co-workers. Adobe Express offers this, but not Rush. ClipChamp from (gulp) Microsoft has this, but not Adobe Rush. ClipChamp is actually very comparable and will probably be the direction we go.

It really does not look like Adobe has put much time or energy in developing Adobe Rush since it is introduction, which promissed collaboration early on as one its upcoming features at the time, which was why we adopted it as a company.
