Yes, I completely agree. Definitely an engineering failure/oversight. Hopefully AMD will make it MANDATORY for all future Reference Designs and also force ALL OEMs to include the multiple CrossFire connectors on ALL current and future graphics cards.
Apparently nobody took into consideration that the PCIe 3.0 bus probably doesn't have enough bandwidth for running at 144GHz, and as we eventually move towards PCIe 4.0, if users are still using a legacy PCIe 3.0 (or PCIe 2.0/2.1) slot, they will still need the multiple CrossFire connector(s) for bandwidth between the various GPU/graphics cards.
Forcing ALL vendors/OEMs to include multiple CrossFire connectors would at least prevent such things from happening in the future.
It's unfortunate that NOBODY at AMD had even thought of this...
