Technically you're right, but I don't think MS is that stupid. Sony already pushed Jaguar to it's limits with PS4 Pro and it still bottlenecks the GPU by a pretty considerable amount. I don't think MS is dumb enough to make the same mistake, the 6 tflop GPU would be a complete waste if they did. They've closely listened to developer feedback from both western and Japanese 3rd party devs while developing it, and I'm sure that many 3rd party devs have been asking for a good CPU due to the bottlenecking issues they've ran into with Jaguar on PS4 and XB1. I think some mobile Excavator cores are the actual bare minimum we will see on Scorpio. 

Jaguar can still be pushed harder, it's far from being at it's limit.
The Athlon 5370 for example had a clockrate of 2.2Ghz vs the PS4 Pro's 2.1Ghz... But the Athlon was also built at 28nm not 16/14nm which should give you some extra clock rate wiggle room at the same TDP... Plus these consoles are using a Semi-Custom chip design, not a direct clone of the PC chips, AMD would be reworking some things, so they could push for higher clock rates.

Bottlenecks aren't really a thing in consoles anyway, developers work around them well enough... Plus bottlenecks will change depending on a games scene/game engine/price of a can of beans in China... Plus everyone keeps ignoring Jaguars real-life successors... Puma and Puma+. - Which can go over the 2.5ghz barrier.

The other option is... Microsoft just throws another 4x Jaguar cores at the problem and goes wider rather than faster, Excavator would probably still be more transistor heavy than Jaguar/Puma or Puma+ though especially if you push for 8 threads.

GPU's are also able to lift some of the work CPU's typically do anyway these days, developers just need to be a little more creative with how they approach it.

I've been wanting to ask someone about this and you are very knowledgeable. Why didn't Sony/Cerny go with Puma+ on the PS4 Pro?

I recall reading that it was more straightforward to keep Jaguar since the logic wouldn't change. Developers woud be tasked with accomodating the extra GPU resources. Since it was a lighter job they would be more likely to support the Pro. Doesn't this imply (assuming Scorpio doesn't keep Jaguar) that it's more tedious to support Scorpio?

I also recall reading that a higher frequency probably would have meant an external power supply. But I'd take a 2.5GHz Puma+ for stable framerates..
