There is quite a margin for ddr4 to safely overclock as many chips are already capable of doing in excess of 4000, and the only reason ecc memory is still stuck at 2666 is jedec never bothered to update their specifications, which they didn't do not because it is unfeasible, but because it is something that they haven't deemed necessary for the time being.
RAM manufacturers care about profits, which is why they go ahead and release "pre-overclocked" modules. So, the lack of ECC at 3Ghz+ is either because:
A. There's some industry regulation I'm not aware of that legally prevents them from doing so.
B. There's no demand (which is BS).
C. Because they can't guarantee performance/reliability - something ECC users care about since that's the sole purpose of ECC.
Anyway - I have no doubt ECC is capable of going higher. But can!=should. This is probably why neither AMD nor Intel offer overclocking on their server platforms.
Power usage is also a concern, especially in high density datacenters, especially when using high capacity fb memory. Enterprise hardware, in general, aims for the optional power\performance ratio, which is also why even low core count server cpus are fairly underclocked, even if they have ample TDP budget to increase per-cpu performance.
