Too bad they have only 2 channel memory controllers and same 32/32 L1 cache. That means all that power is still wasted waiting for memory (Max Memory Bandwidth 45.8 GB/s, seriously?). Not sure why feeling so excited about those processors.

They also still only have 16 PCI-E lanes from the CPU, which is disappointing. Ryzen's 20 isn't exactly lavish, but it's enough for the pair of x16 for the GPU + x4 for the primary NVME drive.
For typical desktop workloads memory bandwidth is not that important. They likely will release Xeon-W counterparts later with similar frequencies but higher memory channels and PCI-E lanes for those who need it.

Perhaps, I need to take that as an axiom, right? i7 5820K was non-typical for that matter then.

And yes, Xeon-W with 5.3GHz frequency? Tell me more :)

The i7-5820K is from the "high end desktop" line of chips, derived from Xeon workstation chips. The modern equivalent is chips like the i9-10900X (note X not K), which does have quad channel DDR4-2933 and 48 PCIe lanes. Clock speeds are a bit lower though.
