I have impression JEDEC constantly underestimate what manufacturers can actually do... I bought last year DDR3 RAM, 2400mhz. So, when DDR4 started to be sold, capped at 2133, DD3 2400 was already sort of easy to find (and it is faster than the DDR4 too, due to smaller latency, the few times I decided to run my computer in some OC competition that relied on RAM it ended on the top 1% of the air cooled machines despite not being an exceptional machine neither prepared to OC, Intel XMP runs crazy fast on my machine, the OC people I talked all said it was because of my fast DDR3 RAM).
