This is a pretty interesting feature - it solves a number of issues/roadblocks with the existing Upwork Agency model.
The requirement to have an established Upwork Network is perhaps the biggest sticking point, though. For those without a network, it's chicken or the egg. Surely you'd rather work with someone first on a team gig before inviting them to your trusted network?
Why go through the effort of inviting a bunch of random people just to create a network? Then, turn around and represent those people to a client? Makes no sense. This generates a lot of invitation spam, too.
In my view, the Upwork Network should be more organic and based on engagements with people you've already worked with or know personally.
Perhaps freelancers could indicate they're "Open to network invitations from Top Rated freelancers" as a proper network-building tool?
