You are right about the socket - ark.intel.com doesn't mention the socket for the two top-end parts. All others use the previous one.
The good news is that the next generation Mac Pro will have a ton of extra memory bandwidth.
And the successors to Cascade Lake seem to switch to the LGA4189 socket to support 8 memory channels (Cooper Lake and Ice Lake), so I wouldn't expect any upgrades on LGA3647.
